It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention. Furthermore, the structures shown in the drawings are often part of actual structures. In particular, the drawings are shown with different emphasis instead being placed upon illustrating the various embodiments.
It is noted that "first", "second", etc. in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects so as to describe embodiments of the present invention, and not to describe a specific order or sequence, it should be understood that the structures so used may be interchanged under appropriate circumstances. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in this embodiment, the frequency band center value corresponding to the GPS is 1575MHz;2.4G WiFi and Bluetooth share 2400-2500 MHz frequency band; the frequency band corresponding to 5.8G WiFi is 5100-5850 MHz.
The embodiment provides a four-in-one antenna assembly, as shown in fig. 1, wherein the four-in-one antenna assembly comprises an antenna main body and a coaxial cable, and the antenna main body is electrically connected with the coaxial cable; the antenna body includes a high frequency unit 110, a connection branch 120, a GPS radiating element 130 and a WiFi radiating element 140; the connection branches 120 are spaced from the high-frequency unit 110, and one end of the connection branches is connected with one end of the high-frequency unit 110 to form a first coupling slot 210, and the other end of the connection branches is connected with one end of the GPS radiating array 130 and one end of the WiFi radiating array 140.
According to the four-in-one antenna assembly provided by the embodiment, 5.8G WiFi frequency band resonance is generated through the high-frequency unit, GPS frequency band resonance is generated through the GPS radiation array, 2.4G resonance can be generated through the WiFi radiation array for WiFi communication and Bluetooth communication, so that four antenna functions can be realized through only one antenna main body, and the integration level of the antenna is improved; meanwhile, the coaxial cable is connected with the antenna main body, so that efficient feeding of the antenna main body is realized; in addition, through adjusting the sizes of the high-frequency unit, the connecting branch, the size, the position, the interval and the like of the GPS radiation array and the WiFi radiation array, tuning of corresponding frequency bands can be achieved, and therefore performance of the antenna is improved. The problem of among the current panel computer antenna integrated level low and the performance is relatively poor is solved.
Specifically, in the present embodiment, the high-frequency unit 110 has a rectangular shape with a long side and a short side. The longitudinal direction of the high-frequency unit 110 is defined as a longitudinal direction. The connection knob 120 is disposed in parallel with the high frequency unit 110 in the length direction. At this time, one end of the connection knob 120 is connected to one corner of the high frequency unit 110, and the first coupling groove 210 is formed adjacent to the long side of the high frequency unit 110. By the arrangement, the tuning range is larger due to the longer long side size, so that better antenna resonance effect is generated.
By adjusting the width and length of the first coupling groove 210, the resonance effect of the GPS radiating element 130 and the WiFi radiating element 140 can be controlled, and in particular, the resonance depths of the GPS and 2.4G WiFi (bluetooth) can be controlled. In this embodiment, the inventors have found through a lot of experiments that the tuning effect is optimal when the width of the first coupling groove 210 is 0.5-4 mm, and the length setting needs to be determined according to the specific application environment and the overall size of the antenna.
Further, the GPS radiating array 130 and the WiFi radiating array 140 are disposed at 180 ° and are parallel to the connecting stub 120 along the length direction. The GPS radiating array 130 and the WiFi radiating array 140 are arranged at 180 degrees, that is, the GPS radiating array 130 and the WiFi radiating array 140 are horizontally arranged, so that the whole space occupied by the antenna main body can be effectively reduced, and the space is saved. In addition, the parallel connection with the connection branch 120 along the length direction can make the size range of resonance generated between the GPS radiating array 130 and the WiFi radiating array 140 and the connection branch 120 larger, which is beneficial to tuning resonance.
In this embodiment, a second coupling slot 220 is formed between the GPS radiating element 130 and the connecting stub 120. The second coupling groove 220 is adjusted to meet the requirement of GPS wavelength, and after the requirement reaches 1/4 wavelength, the first coupling groove 210 is adjusted to finely adjust the resonance depth of the GPS antenna, so that the GPS communication function is realized, and the GPS communication quality is ensured. Specifically, the inventor finds that the resonance effect of the GPS antenna is optimal when the width of the second coupling groove is 0.5-4 mm through a large number of simulation experiments.
And, in this embodiment, a third coupling slot 230 is formed between the WiFi radiating element 140 and the high frequency unit 110. Since the third coupling slot 230 is a gap between the high frequency unit 110 and the WiFi radiating array 140, and the high frequency unit 110 is for implementing 5.8G WiFi communication, and the WiFi radiating array 140 is for implementing 2.4G WiFi communication, tuning can be implemented for both 2.4G and 5.8G WiFi by adjusting the size of the third coupling slot 230. In addition, since the third coupling slot 230 communicates with the first coupling slot 210, the third coupling slot 230 also affects the resonant depths of the WiFi and GPS antennas. It can be seen that the design of the third coupling groove 230 is particularly important in the antenna main body structure provided in the present embodiment. The inventor has found through a large number of simulation and simulation verification that when the width of the third coupling groove is 3-6 mm, the radiation performance of each frequency band of the antenna main body is the best.
Preferably, in this embodiment, a GPS coupling slot 240 is formed at the radiation end of the GPS radiation array 130. The current flowing on the GPS radiating element 130 is coupled through the GPS coupling slot 240, thereby improving the radiation intensity and performance of the GPS signal.
Similarly, in this embodiment, a WiFi coupling groove 250 is formed at the radiation end of the WiFi radiation array 140. The current flowing through the WiFi radiating array 140 is coupled through the WiFi coupling groove 250, thereby improving the radiation intensity and performance of the 2.4G WiFi signal.
Further, the radiation end of the GPS radiation array 130 and the radiation end of the WiFi radiation array 140 are disposed opposite to each other, so that the isolation between the GPS signal and the 2.4G WiFi signal is high, and signal crosstalk is avoided. Meanwhile, the design of the coupling groove and the connection relation is considered, so that the space size occupied by the antenna main body can be effectively reduced.
In order to realize the feeding to the antenna main body, the antenna main body is also provided with a place and a feeding point. Specifically, in this embodiment, a location 111 is disposed on a side of the high-frequency unit 110 close to the WiFi radiating array 140; one end of the connection unit 120, which is connected to the GPS radiating element 130 and the WiFi radiating element 140, is provided with a feeding point 121. The feeding point 121 is disposed at the connection position of the connection unit 120, the GPS radiating array 130 and the WiFi radiating array 140, so that current can be dispersed to each area after flowing out from the feeding point 121, thereby ensuring the radiation intensity and performance of each frequency band. Since the area of the high frequency unit 110 is maximized in the present embodiment, the place 111 is provided at the high frequency unit 110, which is advantageous in that the current of each region flows back to the ground, thereby improving the efficiency of the current.
Further, in this embodiment, the coaxial cable includes a core wire and a shielding layer that are insulated from each other, the core wire is electrically connected to the feeding point, and the shielding layer is electrically connected to the location. The connection of the coaxial cable to the feed point and location is well known to those skilled in the art, for example by means of soldering; and, the structure, size, material, etc. of the coaxial cable can be selected by those skilled in the art according to the actual situation, and will not be described herein. In addition, the other end of the coaxial cable may be connected to the circuit board by a crimp or soldered terminal.
In this embodiment, in order to facilitate connection of the coaxial cable to the feeding point and the place, and avoid risks such as short circuit caused by the exposure of the core wire too long, the feeding point 121 and the place 111 are disposed adjacent to each other.
The embodiment also provides a tablet personal computer, which comprises the four-in-one antenna assembly provided by the embodiment.
According to the tablet personal computer provided by the embodiment, as the four-in-one antenna assembly can generate 5.8G WiFi frequency band resonance through the high-frequency unit, GPS frequency band resonance through the GPS radiation array, and 2.4G resonance for WiFi communication and Bluetooth communication through the WiFi radiation array, four antenna functions can be realized through only one antenna main body, and the integration level of the antenna is improved; meanwhile, the coaxial cable is connected with the antenna main body, so that efficient feeding of the antenna main body is realized; in addition, through adjusting the sizes of the high-frequency unit, the connecting branch, the size, the position, the interval and the like of the GPS radiation array and the WiFi radiation array, tuning of corresponding frequency bands can be achieved, and therefore performance of the antenna is improved. The problem of among the current panel computer antenna integrated level low and the performance is relatively poor is solved.
