An Active Plane Angle Diversity Antenna for Beyond Line-of-sight Wireless Communication

Abstract

The invention discloses an active plane angle diversity antenna for beyond-visual-range wireless communication, and belongs to the technical field of wireless communication and antennas. The antenna comprises M antenna sub-array planes, M one-to-two power dividers, 2M TR assemblies, a first beam control module, a second beam control module, two one-to-M power dividers, two up-down frequency conversion units, two intermediate frequency transmit-receive units, a beam 1 processing circuit, a beam 2 processing circuit and an angle diversity modem. The antenna provided by the invention decomposes the power of the high-power transceiver into the combination of a plurality of low-power modules by adopting an active adjustment mode, so that the design difficulty of a transceiver is reduced. The antenna can be modularly assembled according to use requirements, and the angular diversity multiplying power is flexibly adjusted according to actual use conditions, so that the use flexibility of theangle diversity antenna system is greatly improved, and the application range of beyond-visual-range wireless communication products is expanded.

Description

technical field [0001] The invention belongs to the field of wireless communication and antenna technology, in particular to an active planar angle diversity antenna for wireless communication beyond the line of sight. Background technique [0002] Transcendent line-of-sight wireless communication, because its channel is a diffuse fading channel, the received signal has serious fading. In order to combat the fading of the communication system, diversity means are usually used for signal reception. The common and practical means are space Diversity, the use of space diversity to combat the fading effects of over-the-horizon wireless communication systems has a better effect, but the number of antennas required is large and the size is large, which is not conducive to the light weight of communication equipment and the improvement of mobility. Communication equipment using angle-diversity antennas can use one antenna to achieve the performance of two or more antennas, which ca...

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 it more difficult in performance debugging; in addition, because the parabolic antenna The support structure of the feed source is long, and 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
