摘　　要：提出了一种新型共孔径导航天线。利用不同天线具有不同辐射空间的特点,在低频天线弱辐射区加载高频天线辐射区,两天线辐射区域互补的思路实现共孔径。仿真证明天线辐射性能不仅能够满足两种导航要求,同时两个天线端口之间的隔离度大于82 dB。该设计思路对减少机载平台天线的数量,提高系统集成度具有指导意义。A new common aperture antenna design is presented.Using the characteristics of different antennas with different radiation spaces,the low-frequency antenna’s weak radiation area is loaded with the high-frequency area,and the idea of complementing the two antenna radiation areas realizes a common aperture.Simulation results show stable integration of the far-field radiation characteristics of the antenna,the isolation is more than 82 dB reached.It has a strong significance to reduce the number of airborne antenna platform,improve the integration system.
