本文简要介绍了圆极化天线的特点,同时针对卫星通信系统对圆极化天线的新需求,介绍了圆极化波导天线、宽带双圆极化天线及宽带宽角圆极化相控阵天线的设计,并给出了设计验证实例。所提出的新型圆极化天线对于卫星通信系统、雷达系统都有很高的应用价值。
In this paper, the characteristics of circularly polarized antenna are introduced briefly. At the same time, in view of the new demand for circularly polarized antenna in satellite communication system, circularly polarized waveguide antenna, wideband double circularly polarized antenna and wide bandwidth circularly polarized phased array antenna Design, and gives examples of design verification. The proposed new circularly polarized antenna for satellite communications systems, radar systems have a high value.
