摘　　要：介绍一种W波段调频连续波(FMCW)体制的介质透镜天线,其结构形式简单,性能稳定可靠,解决了调频连续波的较高收发隔离度的要求,天线的收发隔离度可达58dB以上。天线副瓣电平可达-24dB,电压驻波比在1GHz带宽内小于1.5,600MHz带宽内小于1.3,天线效率在整个带宽内可以达到70%以上。The paper presents a W-band FMCW dielectric lens antenna with simple structure and stable reliability so as to meet high requirement for transceiver isolating degree. The transceiver isolating degree of the antenna can be 58dB. The antenna side lobe level can be -24dB. The voltage standing ratio with in 1GHz bandwidth is less than 1.5 and with in 600MHz bandwidth is less than 1.3. The antenna efficiency with in the whole band can be greater than 70%.
