Currently, the overall design of portable electronic devices (such as notebook computers, tablet computers, smart phones, etc.) is increasingly thinner and lighter, and in order to improve the visual experience and holding experience of users, the casing of the portable electronic device is also gradually designed with an all-metal casing. The design of frivolity makes the space that is used for installing the antenna on the portable electronic equipment become smaller and smaller, and all-metal shell causes the shielding to the antenna easily to shelter from, leads to antenna work efficiency low. Therefore, there is an urgent need in the art for a device that is simple in structure, small in size, and adaptable to small space installations.
In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a slot antenna assembly 100, as shown in fig. 1 and 2, including a dielectric substrate 110, a radiation layer 120, the radiation layer 120 is a metal plate, the radiation layer 120 is disposed on one surface of the dielectric substrate 110, the radiation layer 120 has two opposite surfaces, the radiation layer 120 has a slot 121 penetrating through the two surfaces, and a feeding layer 130 is attached to a surface of the dielectric substrate 110 facing away from the radiation layer 120, the feeding layer 130 is used for feeding the radiation layer 120 to excite the radiation layer 120 to emit signals, and the dielectric substrate 110 is used for supporting the radiation layer 120 and the feeding layer 130. Compared with the prior art, the slot antenna is provided with the plate-shaped radiation layer structure with the slots, the radiation layer 120 is arranged on one surface of the dielectric substrate 110 and supported by the dielectric substrate 110, and the feed layer 130 is arranged on one side of the dielectric substrate 110, which is away from the radiation layer 120, so that the whole slot antenna assembly 100 is arranged in a laminated manner, the antenna volume can be reduced, and the antenna structure is easier to design and manufacture and better applied to electronic equipment with an all-metal shell.
The following details of implementation of the slot antenna assembly 100 of the present embodiment are specifically described, and the following details are provided only for facilitating understanding, and are not necessary for implementing the present embodiment.
In this embodiment, the radiation layer 120 is a rectangular plate, the slit 121 extends along the extending direction of the long side of the radiation layer 120, and the length of the slit 121 is 50mm to 90 mm. Specifically, the volume of the slot antenna is much smaller than that of a common antenna, and the slot antenna can better adapt to the requirement of small space. The length of the slot 121 is 50mm to 90 mm (e.g., 50mm, 60mm, 70 mm, 80 mm or 90 mm), that is, the length of the slot antenna provided by the invention can be further adjusted according to practical situations, for example, when the remaining space of the portable electronic device is larger, the slot antenna with larger length can be used, the antenna performance is better, and when the remaining space of the portable electronic device is smaller, the slot antenna with smaller length can be used under the condition of maintaining enough performance.
Further, since the dielectric substrate 110 is mainly used for supporting the radiation layer 120 and is used for connecting with the portable electronic device to fix the radiation layer 120 and the feeding layer 130 relative to the portable electronic device, the dielectric substrate 110 is preferably configured in a rectangular plate shape with the same length as the radiation layer 120, and the length direction of the dielectric substrate 110 is the same as the length direction of the radiation layer 120, so that the radiation layer 120 can be well supported. It will be appreciated that the length of the dielectric substrate 110 may be made smaller or larger than the radiation layer 120 when necessary, for example, when the structure for connecting the dielectric substrate 110 on the portable electronic device is small, the length of the dielectric substrate 110 may be appropriately reduced, and conversely, when the structure for connecting the dielectric substrate 110 on the portable electronic device is large and the remaining space is large, the dielectric substrate 110 having a large length may be used, and thus, other components may be mounted using the remaining space on the dielectric substrate 110.
Alternatively, the dielectric substrate 110 may be a circuit board, or may be a substrate made of an insulating material, preferably plastic, because the plastic has high strength, good elasticity, low density, and light weight.
It can be understood that the radiation layer 120 and the feed layer 130 are disposed on two opposite sides of the dielectric substrate 110, the radiation layer 120 and the feed layer 130 are not directly connected, and the feed layer 130 excites the radiation layer 120 by coupling feeding, so that the radiation layer 120 emits electromagnetic waves.
In this embodiment, the feeding layer 130 includes an input end 131, a first output end 132, and a second output end 133, where the first output end 132 and the second output end 133 are connected to the input end 131, and an area of a front projection of the first output end 132 on the dielectric substrate 110 is smaller than an area of a front projection of the second output end 133 on the dielectric substrate 110.
Further, the lengths of the first output end 132 and the second output end 133 are different.
By setting the first output end 132 and the second output end 133 in the feeding layer 130 to have different areas and different lengths, the outputs of the first output end 132 and the second output end 133 can be different, and the return loss of the radiation layer 120 can be adjusted, so that the radiation layer 120 resonates at different positions in response to different excitation, that is, the radiation layer 120 has two resonant frequencies, and the radiation layer 120 realizes broadband radiation.
In this embodiment, the input end 131, the first output end 132, and the second output end 133 are integrally formed. That is, the feeding layer 130 is integrally designed, so that the fittings of the slot antenna assembly are fewer, and the assembly difficulty of the slot antenna assembly 100 can be reduced.
More specifically, the feeding layer 130 is a two-power divider. The two power splitters are integrally Y-shaped, wherein one end of the input end 131 is connected with an internal circuit or a power supply of the portable electronic device to receive excitation energy, and the other end of the input end 131 is bifurcated into a first output end 132 and a second output end 133. By adopting the two power splitters, the overall structure is simple, and the manufacturing difficulty and the manufacturing cost of the slot antenna assembly 100 can be reduced.

In the present embodiment, the groove 310 extends from the edge of the display panel 300 to the middle of the display panel 300 by 5mm to 10 mm, and the depth of the groove 310 in the thickness direction of the display panel 300 is 2mm to 3 mm.

Taking a notebook computer as an example, the back case 210 is a case of the a-side of the notebook computer, and the front case 220 is a case of the B-side of the notebook computer. Since the slot antenna assembly 100 is disposed at the edge of the display panel 300, that is, the slot antenna assembly 100 is disposed at the edge of the screen of the notebook computer, the housing on the B-side is made of a non-metal material, and the slot antenna assembly 100 can receive external electromagnetic wave signals through the housing on the B-side.
