天线是确定大容量微波系统性能的关键性部件,它必须有效而毫无失真地发送和接收所需信号,必须使干扰信号(包括本系统的它站干扰和其它系统的干扰)减少到容许的电平,而且在任何气象条件下都要有效地工作。所设计的天线应该在制造、试验和安装方面都简化,有关支撑杆的调整和维修也应该很方便。本文叙述一个最近研制的大容量微波系统的天线。其频段为5.925～6.425千兆(6千兆频段低端)和6.410～7.110千兆(6千兆频段高端),此天线代表了满足上述要求的重大发展。
Antenna is the key component to determine the performance of a large-capacity microwave system. It must transmit and receive the desired signal without distortion. The interference signal (including its own station interference and other system interference) must be reduced to the allowable Level, and work effectively under any weather condition. The designed antenna should be simplified in terms of manufacturing, testing and installation, and the adjustment and maintenance of the support bar should also be easy. This article describes an antenna recently developed for large-capacity microwave systems. Its band is 5.925-6.425 gigaBit (6 gigahertz low band) and 6.410-7.110 gigahertz (6 gigahertz band high band), representing an important development that meets the above requirements.
