一种应用于卫星通信的双频双圆极化Fabry-Perot谐振腔天线
An dual-band dual-circularly polarized Fabry-Perot resonant cavity antenna for satellite communication
摘要
Abstract
For the development of high-performance satellite communication antennas,a dual-band dual-circular polarized antenna based on Fabry-Perot resonant cavity is proposed in this paper.The resonant cavity antenna is equipped with two partial reflective surfaces(PRS)on the upper surface.The high gain and circular polarized radiation are achieved by the multiple reflections and in-phase superposition of the electromagnetic wave in the cavity.The designed PRS is based on electromagnetic metasurface technology and has both high pass and low-pass functions,enabling the antenna to achieve dual frequency characteristics.Using a 2×2 angled microstrip patch antenna array as the feed source,the axis ratio is improved with sequential rotation feeding technology.The measurements of the prototype show that the operating bandwidths of the C-band and Ku band are 8.03%and 4.14%,respectively,and the peak gains are 14.78 dBi and 14.52 dBi.The antenna performance meets the requirements of the frequency division duplex satellite communication system,which is suitable for the ground equipment of the future high-speed satellite Internet.关键词
