Abstract

This paper presents a novel single feed Dielectric Resonator Antenna (DRA) exhibiting dual band operation in the Ku-band. The dual band operation is characterized by one circular polarized band centered at 13 GHz with 17.24% 3 dB axial ratio bandwidth and one band at 10.55 GHz with 5.58% 20 dB axial ratio bandwidth, which is basically approximating linear polarization. In both bands, the Dielectric Resonator is excited in its HEM11δ resonant mode. The design features a single feed design utilizing back-side microstrip excitation through novel bowtie cross slots.

ku波段线性和圆极化双频单馈介质谐振器天线

本文提出了一种新型的单馈介质谐振器天线(DRA)，在ku波段具有双频工作特性。双频工作的特点是一个以13 GHz为中心的圆极化频带带宽为17.24%，轴比为3 dB;一个以10.55 GHz为中心的频带带宽为5.58%，轴比为20 dB，基本接近线极化。在两个波段中，介质谐振腔都以HEM11δ谐振模式被激发。该设计采用单馈设计，通过新颖的领结交叉槽利用背面微带激励。
