摘要
针对超高性能要求的微波天线需求,提出了一种低剖面反射面天线的方案,采用F/D<0.2的"深锅"反射面配合一种后馈式自支撑馈源,实现较优的方向图包络,满足ETSI Class3的要求。文中给出了设计思路、方法和一些工程经验,并以0.6 m、15 GHz微波天线为例,利用仿真软件FEKO分析天线的性能,结果表明,仿真结果与测试结果吻合良好。
Considering the requirements of ultra-high performance microwave antenna, a solution of the low profile reflector antenna, with the deep-dish reflector of F/D〈0.2 and a type of rear-feed self-support feed, is proposed, to obtain the high level of radiation pattern envelope, and to meet the requirements of the ETSI Class3. The means and technique of design, and some engineering experience are presented, while the antenna, the 0.6 m/15 GHz microwave antenna as an example, is simulated by the commercial software FEKO. There is a good agreement between the results simulated with those measured as shown.
