It can be seen that the conventional antenna performance dual-parallel module mainly has two independent antennas. When they are combined with each other, better radiation efficiency can be obtained. However, although the efficiency of radio wave radiation is effectively enhanced, it is necessary to fix more antennas 1 in the inner space of the product at the time of manufacture, which is more difficult in configuration.

Therefore, in order to improve the above-mentioned conventional enhanced antenna performance dual-parallel module, the manufacturer has also developed a better antenna. As shown in the second figure, it is a schematic diagram of another conventional antenna. It can be seen that the generation of the antenna 1a is manufactured. In time, it can be faster than the conventional distributed antenna, but although the manufacturing time is increased, the structure of the antenna 1a in the second figure is too complicated, so that distortion is easily generated in the manufacturing process.

With the above technology, the radiation field shape existing for the conventional use may be poor, and because it is not integrally formed, the manufacturing time is also long, and the problem of distortion and deformation easily occurs in the manufacturing process, and the present invention is achieved. The invention is as practical as the above advantages.
