研究了基于阵因子函数的阵列天线设计方法,并成功应用于箭载中继卫星测控天线的设计与实现。本文分析设计了天线单元,推导了柱面共形相控阵阵因子函数,给出了天线阵的阵方向图函数,利用Ansoft HFSS软件进行了仿真优化和验证。样机的微波暗室测试结果表明天线满足工程需求。

This paper studies a method based on conformal phased array antenna.The method has successfully been used in the design and realization of TT&C antenna used on rocket,which completes the tracking telemetry and command by the Tracking and Data Relay Satellite System(TDRSS).The antenna element is first designed,then the array function is induced,and the characteristic function of cylinder phased array antenna is given.The simulation by Ansoft HFSS is used to optimize and validate the design.At last,the results of microwave darkroom testing show that the designed conformal phased array antenna meets the needs of TT&C by TDRSS.
