摘要

提出了一种新的超宽带(1 - 15ghz)正交换能器及其双极化四脊喇叭天线的设计方案。在工作频率范围内，正交换能器的驻波比不超过1.8，天线的驻波比不超过2.1。正交线性极化两个端口之间的隔离度大于40 dB，天线增益在5 ~ 14 dB之间变化。

A high performance ultrawideband orthomode transducer and a dual-polarized quad-ridged horn antenna based on it

A new designs of an ultrawideband (1–15 GHz) orthomode transducer and a dual-polarized quad-ridged horn antenna based on it are presented. In the operating frequency range VSWR of the orthomode transducer doesn't exceed 1.8 and the antenna's VSWR doesn't exceed 2.1. Isolation between two ports with orthogonal linear polarizations is higher than 40 dB and the antenna's gain varies from 5 to 14 dB.
