Problems solved by technology
[0003] At present, the traditional angle-diversity antenna adopts the parabolic antenna to realize the structural form of the angle-diversity feed. After the magnification of the angle-diversity feed is determined, it cannot be adjusted in subsequent use, which makes performance debugging more difficult.
In addition, due to the long support structure of the parabolic antenna feed, the storage height of the antenna is high when it is loaded into the car, which is inconvenient to use, and its usage scenarios will be greatly restricted

Description
technical field [0001] The invention belongs to the field of wireless communication and antenna technology, in particular to a plane angle diversity antenna for wireless communication beyond the line of sight. Background technique [0002] For trans-horizon wireless communication, because its channel is a diffuse fading channel, the received signal has serious fading. In order to counteract the fading of the communication system, diversity means are usually used for signal reception. The commonly used and practical method is space diversity. The use of space diversity to combat the fading effects of over-the-horizon wireless communication systems has a good effect, but the number of antennas required is large and the volume is large, which is not conducive to the lightness and mobility of communication equipment. Performance improvements. Communication equipment using angle-diversity antennas can use one antenna to achieve the performance of two or more antennas, which can ...
