摘要
针对在散射通信中角分集天线的设计与应用问题,从理论上对角分集馈源采用垂直分布条件下的仰角偏移损耗与天线波束宽度、波束仰角及其他链路参数的关系进行了分析,并对由波束之间的相关性导致的相关损耗进行了仿真,在此基础上提出了一种基于角分集增益最大化的垂直分布波束之间的最佳夹角设计准则。结合具体散射链路特征,给出了角分集天线采用垂直分布波束条件下波束之间的最佳夹角设计实例。
Aimed at the design and application of angle diversity antennas in troposcatter communication, the relationship with squint loss, beam width, squint angle and other link parameters is derived firstly, and the beam correlation loss is simulated subsequent- ly. Based on the analysis above,a principle is presented about the selection of best squint angle aimed at the maximum gain of an angle diversity antenna. In the end, an example is presented about the best squint angle of a dual-feedhorn antenna with vertically distributed squint beams based on a specific troposcatter link.
