弹载遥测系统天线设计

内容简介：飞行导弹的特殊应用环境对弹载天线设计提出了特殊的要求，本文以飞行导弹弹载数据遥测为应用背景，对弹载发射天线方案进行分析比较和优化，设计了一种S波段圆极化共形微带天线方案，克服目前弹载天线安装困难、频带窄，易受干扰等缺点。天线的有效工作频带展宽为2243~2263 MHz，中心频率为2250.5 MHz，工作频段内电压驻波<2。采用ANSOFT HFSS软件进行天线性能仿真、测试，表明该弹载天线安装方便，在高冲击高过载条件下天线性能指标优良，所选方案切实可行，可应用于不同设备的遥测和弹载天线应用中。

Abstract： The special application environment of flight missile presents special requirements on the design of the shell-carried antenna.This paper analyzes and optimizes the shell-carried antenna program in the background of flight missiles data telemetry.And designed a conformal S-band circularly polarized microstrip antenna,overcoming the current shortcomings of difficult installation,narrow band,easy interference.The effective working bandwidth of the antenna is 2243~2263 MHz,and the center frequency is 2250.5 MHz.The voltage standing wave is less than 2 under the working frequency.The HFSS simulation result indicates that the onboard antenna can easy installation,as well as excellent antenna performance indicators under high overload,high impact conditions.This design is feasible,which can be applied to telemetry different devices and onboard antenna applications.
