As shown in fig. 1, the antenna includes an antenna body 1 and a transmission element 2 attached to a clearance area corresponding to the antenna body 1, wherein the clearance area is defined by a clearance area; the clearance area is used for isolating the antenna body from other metal devices of the electronic equipment so as to avoid the influence of the other metal devices on the communication of the antenna body and ensure the communication effect of the antenna; the transmission assembly 2 is made of conductive auxiliary materials such as aluminum foil, conductive cloth, and the like, and the antenna of the embodiment of the present application can be manufactured at a low cost.
Moreover, the transmission component 2 is attached to the clearance area of the antenna body 1 through the adhesive material, wherein the transmission component 2 is attached to the clearance area of the antenna body 1 and can be operated outside the factory, so that the in-factory assembly time can be reduced, that is, the antenna provided by the embodiment of the application does not need to additionally increase other process flows, and the manufacturing efficiency is improved at a lower cost. Moreover, the transmission assembly 2 of the embodiment of the present application is directly attached to the clearance area corresponding to the original antenna body 1, and the clearance area does not need to be separately and additionally arranged, so that the original space design of the electronic device is not affected, and the setting of the high screen ratio of the electronic device is not affected.
Further, the transmission assembly 2 comprises a first transmission member 21 and/or a second transmission member 22, and the first transmission member 21 and the second transmission member 22 are used for adjusting the radiation characteristics of the antenna body.

It should be noted that the first transmission member 21 is a reflector, and the second transmission member 22 is a guide, but the first transmission member 21 may also be a guide, and the second transmission member 22 is a reflector, which is not limited in this embodiment of the present invention.
As shown in fig. 2, the first transmission member 21 and the second transmission member 22 are rectangular, and in the case that the transmission assembly 2 includes the first transmission member 21 and the second transmission member 22, the first transmission member 21 and the second transmission member 22 form an L shape or a L-like shape, and preferably, a second end of the second transmission member 22 is attached to a first end of the first transmission member 21. In this regard, one end of the second transmission member 22 is attached to any position of the first transmission member 21, that is, the attachment position between the first transmission member 21 and the second transmission member 22 is adjustable, for example, for different types of electronic devices, different models of the same electronic device, and the like, the attachment position between the first transmission member 21 and the second transmission member 22 can be adaptively adjusted, so that the transmission assembly 2 can conform to the design of the antenna, referring to fig. 2, the dotted lines indicate a plurality of positions of the second transmission member 22, and those skilled in the art should know that fig. 2 is only a possible example.
With continued reference to the schematic structural diagram shown in fig. 2, the first side 211 of the first transmission element 21 is larger than the second side 221 of the second transmission element 22, and at this time, the first side 211 of the first transmission element 21 may be set to 21-41mm, preferably 31mm, which is used for adjusting the low-frequency radiation characteristic of the antenna body 1; the second side 221 of the second transmission member 22 may be provided to be 6-26mm, preferably 16mm, for adjusting the high frequency radiation characteristic of the antenna body 1.
In the specific implementation, the shapes and the sizes of the first transmission piece 21, the second transmission piece 22 and the transmission component 2 are designed by electromagnetic simulation software according to the environment, and then the transmission component 2 formed by the first transmission piece 21 and/or the second transmission piece 22 is attached to the electronic equipment, and the shapes, the sizes and the like are adjusted according to the attachable environment and the material; then, the adjusted transmission assembly 2 is used to perform actual measurement of the wireless transmission throughput, and the shapes and sizes of the first transmission member 21, the second transmission member 22 and the transmission assembly 2 are optimized according to the wireless transmission throughput obtained by the actual measurement, so as to obtain a better shape, size and the like.
The transmission assembly is tested through electromagnetic simulation software, fig. 3A shows a two-dimensional field pattern of a 2.4GHz antenna when the transmission assembly is not set, fig. 3B shows a two-dimensional field pattern of a 2.4GHz antenna after the transmission assembly is set, fig. 4A shows a two-dimensional field pattern of a 5.15GHz antenna when the transmission assembly is not set, fig. 4B shows a two-dimensional field pattern of a 5.15GHz antenna after the transmission assembly is set, fig. 5A simultaneously shows two-dimensional field patterns of a 2.4GHz antenna before and after the transmission assembly is set, and fig. 5B simultaneously shows two-dimensional field patterns of a 5GHz antenna before and after the transmission assembly is set.
