一种新型C波段轻型低副瓣线阵天线

内容简介：对一种C波段轻型低副瓣线阵天线进行了简要介绍。天线采用创新型的准空气带状线结构，通过对天线单元和馈电网络的独立分析设计，并对线阵进行一体化设计和实验研究，使线阵在18％的工作频带内获得了-27 dB的低副瓣性能，与微带结构产品相比，具有轻型化、抗干扰的特点。天线采用模块化设计理念，实现了线阵的快速插拔，提高了产品的通用性和可维护性，目前已成功应用于相控阵雷达天线。

Abstract：A novel design of lightweight,low-sidelobe linear array operating in C band is proposed in the paper. The antenna ele-ment and the network are designed and optimized both in a separate and integrated way. With a quasi-air-stripline network,the prototype antenna achieves a very low level of sidelobe of-27 dB. Compared with its microstripline-type counterpart,the new design is character-ized by reduction in weight and susceptibility. The implementation of module design makes possible the plug and play of the linear array,which improves versatility and maintainability. So far,the antenna has found application in phased array radar system.
