| 摘 要： | 为实现高增益低旁瓣的定向天线,设计了一种采用介质基片集成波导实现缝隙天线阵,并在辐射缝隙两边增加扼流槽,与传统的介质基片集成波导相比,大幅增加了带宽。最后实现了一介质基片集成波导天线阵,其带宽增加了8%,实际测试表明该天线具有高增益,低旁瓣,达到了设计要求。

| Abstract: | In order to achieve a high-gain and low sidelobe antenna,a substrate integrated waveguide antenna array is designed.Choke Grooves are added between two neighboring radiation waveguides.Compared with traditional SIW slot antenna array,this improvement can greatly extend the operational bandwidth.SIW slot antenna array which meets both low side lobe and return loss requirement in desired bandwidth(8%)The experiments show that this antenna has good performance,and achieve the design requirement. |
