Ku波段波导混合缝隙阵列全向天线的设计与实现

Design and implementation of a waveguide hybrid slot array omni-directional antenna at Ku-band

研究并设计了一个工作在Ku波段的波导混合缝隙阵列全向天线.利用电磁仿真软件CST进行仿真设计,采用边馈形式,通过同时对波导的宽边和窄边开缝进行缝隙天线阵列设计,使设计的Ku波段的波导混合缝隙阵列全向天线具有良好的匹配、较高的增益和较好的不圆度,并对设计的天线进行实际加工制造、调试,最终仿真与实测结果能够较好地吻合.

A waveguide hybrid slot array omnidirectional antenna which works at the Ku-band was researched and realized by electromagnetic simulation software CST. The antenna is fed at edge and designed with waveguide broad and narrow brimmed slots array antenna, so as to have good matching characteristic, high gain and good un-round- ness. At last, the designed antenna was fabricated and debugged. The experimental result was in good agreement with simulation data.
