It will be understood that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to FIG. 1 , a schematic diagram of an antenna provided by an embodiment of the present application is shown. Referring to FIG. 2 , a schematic diagram of an antenna provided by an embodiment of the present application is shown. Referring to FIG. 3 , a schematic diagram of an antenna provided by an embodiment of the present application is shown. The third schematic diagram of an antenna provided in the application embodiment. As shown in FIGS. 1 to 3 , the antenna includes: a first branch 10 , a second branch 20 and a substrate 30 .

The first branch 10 and the second branch 20 are both arranged on the base plate 30, and the first branch 10 and the second branch 20 are located on the same side of the base plate 30. The first branch 10 and the second branch 20 have complementary shapes, wherein, Graphical complementarity means that the space surrounded by the first branches 10 is the first shape, at least part of the second branches 20 is located in the space, and the shape of the second branches 20 is the same as the first shape. The second branch 20 includes a plurality of array units 22 and a feeder line 21. The feeder line 21 is arranged in the substrate 30. The plurality of array units 22 are spaced on the substrate 30. The plurality of array units 22 are opposite to the feeder lines 21, and there are multiple array units 22. Array units 22 are located in the space. The first branch 10 is provided with a first feed port 101, and one end of the feeder line 21 is connected to a second feed port 201. The first feed port 101 is used to feed WIFI 2.4G signals and WIFI 5G signals. The first branch 10 is used to radiate the WIFI 2.4G signal and the coupled WIFI 5G signal. The second feed port 201 is used to receive the coupled WIFI 5G signal of the first branch 10. The array unit 22 is used to radiate the WIFI 5G signal. signals and receive millimeter wave signals.

In the embodiment of the present application, since the second branch 20 includes a feeder line 21 and a plurality of array units 22, the feeder line 21 is disposed in the substrate 30, and the plurality of array units 22 are disposed at intervals on the substrate 30. The plurality of array units 22 are Opposite to the feed line 21, therefore, when the array unit 22 receives a millimeter signal, the array unit 22 can transmit the millimeter wave signal to the feed line 21, so that the feed line 21 can transmit the millimeter wave signal to the second feed port. 201. In addition, since the first branch 10 and the second branch 20 are located on the same side of the base plate 30, the first branch 10 and the second branch 20 are graphically complementary, that is, the space surrounded by the first branch 10 is the first shape, at least partially. The second branch 20 is located in this space, and the shape of the second branch 20 is the same as the first shape. The first feed port 101 is provided on the first branch 10. Therefore, the WIFI 2.4G signal and the WIFI 5G signal can After feeding into the first feed port 101, the first branch 10 can radiate the WIFI 2.4G signal. In addition, the first branch 10 can couple the WIFI 5G signal to the second feed port 201 and transmit it through the second feed port. The electrical port 201 is transmitted to the feeder line 21, and the feeder line 21 transmits the WIFI 5G signal to the array unit 22, so that the array unit 22 radiates the WIFI 5G signal. That is to say, in the embodiment of the present application, by arranging the first branch 10 and the second branch 20, both WIFI 2.4G and WIFI 5G signals can be radiated, and the second branch 20 can also receive millimeter wave signals. Signals, electronic devices can be charged through millimeter wave signals, so that the functions of radiating WIFI 2.4G and WIFI 5G and the function of receiving millimeter waves can coexist, so that the antenna has the function of radiating WIFI 2.4G and WIFI 5G signals. It also has the function of receiving millimeter waves, so that when one antenna is placed in an electronic device, two functions can be achieved, thereby facilitating the placement of the antenna in the electronic device.

It should be noted that in the embodiment of the present application, the substrate 30 may be FR-4, where FR-4 is a code for a flame-resistant material grade, which means that the resin material must be able to self-extinguish after being in a burning state. A material specification, it is not a material name, but a material grade.

In addition, in the embodiment of the present application, when the plurality of array units 22 are located in a space with a first shape surrounded by the first branch 10 , at this time, the space can also enable the second branch 20 to have a certain electrical power. The boundary condition, that is, the edge of the space can be used as the electrical boundary of the second branch 20, thereby avoiding the impact of the complex internal environment of the electronic device on the second branch 20 when the antenna is installed in the electronic device, thereby making it easier to install the antenna. After being installed in electronic equipment, the reliability of the antenna is higher, that is, the second branch 20 has a better reception effect of receiving millimeter waves.

In addition, in the embodiment of the present application, since the feeder line 21 is located in the substrate 30 and the array unit 22 is located on the substrate 30, the plurality of array units 22 are not connected in series through the feeder line 21, thereby preventing the array unit 22 from being fed. The wires 21 are connected in series, so that when the feeder wire 21 transmits signals, the array unit 22 consumes the energy of the transmitted signals. Among them, if multiple array units 22 are connected in series through the feeder line 21, at this time, when the feeder line 21 transmits a signal, the signal is essentially an electrical signal. Therefore, the electrical signal will be directly transmitted to the array unit 22, and the consumed part of the array unit 22 Electrical signals affect the transmission of electrical signals.

In addition, in some embodiments, the array unit 22 may be an antenna patch, wherein, as shown in FIG. 1 , the antenna patch may be circular. Of course, the antenna patch can also have other shapes. For example, the antenna patch can be a triangle or a rectangle. The embodiment of the present application does not limit the shape of the antenna patch here.

In addition, in some embodiments, the first branch 10 may be a whole, and the substrate 30 may have a mounting surface. In this case, the first branch 10 may be disposed on the mounting surface in the following manner: the first branch 10 may be glued Connected to the mounting surface, of course, the first branch 10 can also be disposed on the mounting surface in other ways. For example, the first branch 10 is disposed on the mounting surface by welding. The embodiment of the present application does not limit the manner in which the first branch 10 is arranged on the installation surface.

In addition, the array unit 22 may be disposed on the mounting surface in such a manner that the array unit 22 is bonded to the mounting surface. Of course, the array unit 22 can also be disposed on the mounting surface in other ways. For example, the array unit 22 can be disposed on the mounting surface by welding. The embodiment of the present application does not limit the manner in which the array unit 22 is arranged on the mounting surface.

In addition, in some embodiments, the first branch 10 may include an opposite first end 11 and a second end 12, the first feed port 101 is located between the first end 11 and the second end 12, and the first feed port 101 is located between the first end 11 and the second end 12. The electrical port 101 is close to the first end 11 . The length of the first branch 10 is N times the quarter wavelength of the frequency band corresponding to WIFI 2.4G, and N is a positive integer greater than or equal to 1, where the length of the first branch 10 refers to the first feed port The distance between 101 and the second end 12.

When the length of the first branch 10 is N times the quarter wavelength of the frequency band corresponding to WIFI 2.4G, at this time, after the WIFI 2.4G signal can be fed into the first feed port 101, it is convenient for the first branch to Section 10 radiates WIFI 2.4G signal. That is, by setting the length of the first branch 10 to an integer multiple of a quarter wavelength of the frequency band corresponding to WIFI 2.4G, it is convenient for the first branch 10 to radiate the WIFI 2.4G signal.

As shown in Figure 1, the length of the first branch 10 is L, and L is an integer multiple of a quarter wavelength of the frequency band corresponding to WIFI 2.4G. For example, the wavelength of the frequency band corresponding to WIFI 2.4G is 100 mm. At this time, a quarter of the wavelength is 25 mm, and L is an integer multiple of 25 mm. For another example, if L is 3 times 25 mm, then L is 75 mm. For another example, if L is 4 times 25 mm, then L is 100 mm.

In addition, in some embodiments, the distance between the first end 11 and the second feed port 201 is less than 3 mm.

After the first feed port 101 feeds the WIFI 2.4G and WIFI 5G signals, the first branch 10 radiates the WIFI 2.4G signal, but the first branch 10 can feed the WIFI 5G signal into the third branch through coupling. The two feed ports 201, that is, the first branch 10 and the second branch 20 enable the first branch 10 to couple the WIFI 5G signal to the second feed port 201 through the electric field mechanism, so that the second feed port 201 couples the WIFI 5G signal to the second feed port 201. The signal is transmitted to the feeder line 21 and passed to the array unit 22 through the feeder line 21, and the WIFI 5G signal is radiated through the array unit 22. Since the first branch 10 feeds the WIFI 5G signal into the second feed port 201 through the electric field mechanism, therefore, in the embodiment of the present application, the distance between the first end 11 and the second feed port 201 is less than 3 mm. , it can avoid the problem that the distance between the first branch 10 and the second feed port 201 is too large and the first branch 10 cannot feed the WIFI 5G signal into the second feed port 201. That is to say, by setting the distance between the first end 11 and the second feed port 201 to be less than 3 mm, the first branch 10 can be facilitated to feed the WIFI 5G signal into the second feed port 201, thereby facilitating the second feed port 201. Branch 20 radiates WIFI 5G signals.

As shown in FIG. 1 , the distance between the first end 11 and the second feed port 201 is L, and L is any value less than 3 mm. For example, L can be 2.5 millimeters, 2 millimeters, 2.1 millimeters, 1.8 millimeters, 1.5 millimeters, or 0.5 millimeters. The specific value of L is not limited in the embodiments of this application.

In addition, in some embodiments, the length of the second branch 20 is M times a quarter wavelength of the frequency band corresponding to WIFI 5G, and M is a positive integer greater than or equal to 1, where the length of the second branch 20 refers to is the distance between the two ends of the feeder line 21.

When the length of the second branch 20 is M times the quarter wavelength of the frequency band corresponding to WIFI 5G, at this time, it is convenient for the second feed port 201 to feed the WIFI 5G signal and transmit the WIFI 5G signal to After the array unit 22, it is convenient for the array unit 22 to radiate the WIFI 5G signal. That is to say, by setting the length of the second branch 20 to M times the quarter wavelength of the frequency band corresponding to WIFI 5G, it is convenient for the second branch 20 to radiate the WIFI 5G signal.

For example, the wavelength of the frequency band corresponding to WIFI 5G is 40 mm. At this time, a quarter wavelength is 10 mm. The length of the second branch 20 can be three times the quarter wavelength. Then the length of the second branch 20 is 30mm. For another example, if the length of the second branch 20 is twice the quarter wavelength, then the length of the second branch 20 is 20 mm.

In addition, in some embodiments, the distance between two adjacent array units 22 is half the wavelength of the millimeter wave. The distance between two adjacent array units 22 refers to the distance between two centers of two adjacent array units 22 .

When the distance between two adjacent array units 22 is half the wavelength of the millimeter wave, at this time, it is convenient for the array unit 22 to receive the millimeter wave signal and transmit the millimeter wave signal to the feeder 21. It is transmitted to the second feed port 201 through the feed line 21 .

As shown in FIG. 1 , the distance between two adjacent array units 22 is L1, and the specific length of L1 may be equal to half the wavelength of the millimeter wave. For example, the wavelength of a millimeter wave is 2 millimeters. At this time, L1 can be 1 millimeter. For another example, the wavelength of the millimeter wave is 1.5 mm. At this time, L1 is 0.75 mm.

Additionally, in some embodiments, the antenna further includes multiple phase shifters. Multiple phase shifters are arranged on the mounting surface, and one phase shifter is arranged between two adjacent array units 22 . Among them, the phase shifter is used to adjust the phase angle of the millimeter wave.

After the antenna is installed in the electronic device, the orientation of the second branch 20 may be different from the transmission direction of millimeter waves, which may cause problems that affect the reception of millimeter waves by the second branch 20 . In the embodiment of the present application, a phase shifter is provided between two adjacent array units 22. The phase shifter can adjust the phase angle of the millimeter wave, so that millimeter waves at any angle can be received by the second branch 20. The second branch 20 is provided with a beam scanning function. That is, by arranging a phase shifter between two adjacent array units 22, the second branch 20 can receive millimeter waves at any angle, so that the second branch 20 has the function of beam scanning, so that the second branch 20 can 20 can receive millimeter waves in any direction, thereby realizing the function of charging electronic devices through the second branch 20 .

In addition, in some embodiments, the number of array units 22 is an integer multiple of the target ratio, where the target ratio is the ratio of the frequency band corresponding to millimeter waves to the frequency band corresponding to WIFI 5G.

When the number of array units 22 is an integer multiple of the ratio of the frequency band corresponding to millimeter waves to the frequency band corresponding to WIFI 5G, at this time, it can be convenient for the second branch 20 , that is, multiple array units 22 to receive millimeter waves or radiate WIFI 5G Signal.

For example, the frequency band corresponding to millimeter wave is 40GHz, the frequency band corresponding to WIFI 5G is 5GHz, the ratio of the frequency band corresponding to millimeter wave to the frequency band corresponding to WIFI 5G is 8, and the number of array units 22 is an integer multiple of 8. For another example, the number of array units 22 is three times 8. In this case, the number of array units 22 is 24. For another example, the number of array units 22 is one time of 8. In this case, the number of array units 22 is 8.

Additionally, in some embodiments, array unit 22 is coupled to feed line 21 .

When the array unit 22 is coupled to the feeder line 21 , the array unit 22 can transmit the signal to the feeder line 21 so that the feeder line 21 can transmit the signal to the second feeder port 201 .

It should be noted that the distance between the array unit 22 and the feed line 21 may be less than 1 mm to ensure that the array unit 22 and the feed line 21 can be coupled. That is, the distance between the array unit 22 and the feeder line 21 is greater than 0 and less than 1 mm.

When the distance between the array unit 22 and the feeder line 21 is less than 1 mm, the distance between the array unit 22 and the feeder line 21 is relatively close, which facilitates the second feeder port 201 to feed the WIFI 5G signal. The second feed port 201 transmits the WIFI 5GDE signal to the feeder line 21, and the feeder line 21 transmits the WIFI 5G signal to the array unit 22, so that the array unit 22 can radiate the WIFI 5G signal. In addition, when the array unit 22 receives a millimeter wave signal, it is also convenient for the array unit 22 to transmit the millimeter wave signal to the feeder line 21 , so that the feeder line 21 transmits the millimeter wave signal to the second feed port 201 . That is to say, by setting the distance between the array unit 22 and the feeder line 21 to be less than 1 mm, it can be avoided that the distance between the array unit 22 and the feeder line 21 is too large, making the signal transmission between the array unit 22 and the feeder line 21 more difficult. The problem of difference occurs, thereby facilitating signal transmission between the array unit 22 and the feeder line 21 .

It should be noted that, as shown in FIG. 3 , the distance between the array unit 22 and the feeder line 21 is L2, and L2 is any value less than 1 mm. For example, L2 can be 0.8 mm, it can be 0.5 mm, it can be 03 mm, it can also be 0.1 mm. The specific value of L2 is not limited in the embodiment of the present application.

Additionally, in some embodiments, the thickness of the substrate 30 ranges from 1.5 mm to 2.5 mm.

When the thickness of the substrate 30 ranges from 1.5 mm to 2.5 mm, the substrate 30 can be thinner, so that the antenna can be thinner, which is beneficial to the thinning of the electronic device after the antenna is installed in the electronic device.

As shown in Figure 3, the thickness of the substrate 30 is H, and the value of H can be set according to actual needs. For example, H can be 1 millimeter, H can also be 2 millimeters, it can also be 2.5 millimeters, or it can be 1.5mm, also 2.3mm. The specific value of the thickness of the substrate 30 is not limited in this embodiment of the present application.

In addition, since the first branch 10 and the second branch 20 are located on the same side of the base plate 30, the first branch 10 and the second branch 20 are graphically complementary, that is, the space surrounded by the first branch 10 is the first shape, at least partially. The second branch 20 is located in this space, and the shape of the second branch 20 is the same as the first shape. The first feed port 101 is provided on the first branch 10. Therefore, the WIFI 2.4G signal and the WIFI 5G signal can After feeding into the first feed port 101, the first branch 10 can radiate the WIFI 2.4G signal. In addition, the first branch 10 can couple the WIFI 5G signal to the second feed port 201 and transmit it through the second feed port. The electrical port 201 is transmitted to the feeder line 21, and the feeder line 21 transmits the WIFI 5G signal to the array unit 22, so that the array unit 22 radiates the WIFI 5G signal. That is to say, in the embodiment of the present application, by arranging the first branch 10 and the second branch 20, both WIFI 2.4G and WIFI 5G signals can be radiated, and the second branch 20 can also receive millimeter wave signals. Signals, electronic devices can be charged through millimeter wave signals, so that the functions of radiating WIFI 2.4G and WIFI 5G and the function of receiving millimeter waves can coexist, so that the antenna has the function of radiating WIFI 2.4G and WIFI 5G signals. It also has the function of receiving millimeter waves, so that when one antenna is placed in an electronic device, two functions can be achieved, thereby facilitating the placement of the antenna in the electronic device.
