摘要

提出了一种紧凑的上层结构作为圆极化滤波器来设计圆极化共振增益天线(RGA)。采用双馈圆柱介质谐振器天线(CDRA)作为主辐射体设计了CP RGA。在20%轴比(AR)和匹配带宽下，最大CP增益可达15 dBi。旁瓣(<;-15 dB)和交叉电平(<;-22 dB)看起来相当令人满意。

Simple and new design of resonance gain antenna for circular polarization with improved characteristics

A compact superstrate geometry as a circular polarizer filter has been proposed to design a circularly polarized (CP) resonance gain antenna (RGA). A dual-fed cylindrical dielectric resonator antenna (CDRA) has been used as a primary radiator to design a CP RGA. Maximum of 15 dBi CP gain has been achieved over 20% axial ratio (AR) as well as matching bandwidth. The side lobe (<;-15 dB) as well as cross-pol levels (<;-22 dB) appear quite satisfactory.
