摘要
本文提出了一种毫米波低副瓣透镜天线,该天线主要包括介质透镜、馈源喇叭和支撑架三个部分。透镜采用传统的聚四氟乙烯材料(εr=2.05),馈源采用传统的角锥喇叭,支撑架采用金属制成。对天线进行了仿真和测试。测试结果表明该天线实现了在215GHZ-217GHZ频段内增益≥36dB和副瓣电平≤20dB的方向图。
This paper proposes a millimeter wave low-sidelobe lens antenna.The antenna mainly includes three parts:a lens,a feed horn and a support frame.The lens is made of traditional PTFE material(εr=2.05),the feed source is a traditional pyramid cone,and the support frame is made of metal.The antenna was simulated and tested.The test results show that the antenna achieves a pattern with gain≥36 dB and sidelobe level≤20 dB in the 215 GHZ-217 GHZ frequency band.
