摘要

为了获得一种具有低交叉极化分量的多频段新型喇叭，在喇叭的孔径处加载一根锥形轴对称介质杆，并在圆形孔径周围加载同轴槽。因此，本文设计了一种具有两种不同类型波导端口的喇叭，分别用于12/14 GHz (Ku频段)和20/30 GHz (Ka频段)的馈电信号，并对每个频段的频率特性进行了评估。

A Multi-Band Dielectric-Loaded Horn Antenna with Two Feed Systems

For obtaining a novel horn with low cross-polarization components over multiple frequency bands, an axially symmetric dielectric rod with a tapered profile is loaded in the horn up to the aperture, and coaxial grooves are also loaded around the circular aperture. Thus, this paper presents a designed horn with two different types of waveguide-ports for feeding signals for 12/14 GHz (Ku band) and 20/30 GHz (Ka band), respectively, and evaluates the frequency characteristics at each band.
