The first reflector, the second reflector, the third reflector, and the fourth reflector do not share the ground with the first dipole antenna and the second dipole antenna. It should be noted that in the embodiment of the present invention, the model of the controller is not specifically limited, for example, a chip with at least 8 pins can be included, and a high level or a low level can be output to the eight pins, thereby controlling the on and off of the pin diode connected to the corresponding pin. Take the first reflector and the second reflector as an example: when a high level V5 is input to the first reflector end and a high level V6 is input to the second reflector end, the fifth switch unit D5 is in the on state and the sixth switch unit D6 is in the on state, and the first and second reflectors are effective; when a high level signal is input to the first radiating part V1 and the second radiating part V2, or a high level signal is input to the third radiating part V3 and the fourth radiating part V4, the first switch unit D1, the second switch unit D2, the fifth switch unit D5, and the sixth switch unit D6 are in the on state, and the first dipole antenna or the second dipole antenna is effective.

[0062] The Pin diode is marked with "1" when it is working and "0" when it is not working. The influence of the on and off of different switch units on the radiation pattern of the antenna is shown in the following table. The radiation pattern of the antenna numbered 1-14 in the following table is as follows Figure 8-21 As shown;

[0063]

[0064]

[0065] In an embodiment of the present invention, the gain of the antenna can be switched between 2dBi and 7.7dBi, and the maximum gain radiation direction of the antenna can be switched in azimuth to cover different areas of the flat layer, and the radiation direction can also be changed in elevation to meet the leap-layer coverage requirements. At the same time, the antenna can achieve a beam shape that has both a high-gain directional working mode and a wide-beam coverage mode. The antenna can produce a total of 256 radiation patterns to meet different needs. For example, the antenna can be switched from an omnidirectional radiation mode to a directional radiation mode to meet the needs of different usage scenarios. When a wide range of angles needs to be covered, the antenna can work in a wide beam or omnidirectional radiation mode; when point-to-point transmission is required, the antenna can work in a high-gain narrow beam mode to increase the gain in the direction of the communication object, and at the same time reduce the gain in other directions to suppress interference. In addition, the antenna also has a multi-beam mode to meet the needs of point-to-multipoint transmission.
