摘要

提出了一种基于多层介质衬底加工技术的端射双圆极化天线。该天线采用SIW传输线设计，通过在传输线末端增加阶梯介质匹配结构，使天线的阻抗带宽达到20%以上(27-33 GHz)，两个端口之间的隔离度均高于20 dB。在上述带宽范围内，天线轴向比小于3db。通过在HFSS中设置主从边界，天线阵列可以在上述频率范围内实现±30°波束扫描。

An End-Fire Dual Circularly Polarized Antenna for Millimeter-Wave Applications

An end-fire dual circularly polarized antenna based on multilayer dielectric substrate processing technology is proposed in the paper. The antenna is designed with SIW transmission line, by adding a stepped dielectric matching structure at the end of the transmission line, the antenna achieves an impedance bandwidth of more than 20% (27–33 GHz), and the isolations between two ports are higher than 20 dB. Within the above bandwidth, the axial ratio of the antenna is less than 3 dB. By setting the master-slave boundary in HFSS, the antenna array can realize ±30° beam scanning in the above frequencies.
