摘要

本文提出了一种高增益圆极化谐振腔天线(RCA)。采用孔径耦合微带天线(ACMA)作为基本天线，采用由圆形贴片阵列组成的频率选择表面作为上盖。与8.2 GHz的微距贴片相比，所提出的RCA提供了高达12 dB的增益增强。本文详细介绍了RCA的设计。天线的最终增益为20.5 dBic，轴比带宽(AR < 3dB)为200mhz。该高增益CP天线可用于遥感卫星x波段有效载荷数据传输系统。

High gain circularly polarized resonance cavity antenna at X-band

In this paper, a high gain and circularly polarized (CP) resonance cavity antenna (RCA) is proposed at X-band. An aperture coupled microstrip antenna (ACMA) is used as the basic antenna and a frequency selective surface, consisting of an array of circular patches is used as superstrate. The proposed RCA provides a gain enhancement upto 12 dB compared to the microstip patch at 8.2 GHz. A detailed design of the RCA is explained in this paper. Final gain of the antenna is 20.5 dBic, and axial ratio band width (AR < 3dB) of 200 MHz. This high gain CP antenna can be used for payload data transmission system of remote sensing satellites at X-band.
