| 摘 要： | 提出了一种加载S型缝隙的方形切角毫米波微带天线。该天线的辐射贴片采用方形切角,在贴片中央进行非对称S型缝隙开槽,实现了双频点圆极化。在接地板上进行阶跃型缝隙开槽,改变了微带天线的辐射特性及阻抗特性。同时采用加载调谐支节的耦合馈电方式,实现了微带贴片天线频带的展宽。

| Abstract: | In this paper,a novel microstrip antenna with S-shaped slot in millimeter-wave is presented. This antenna has a simple structure with coupling feed and a stepped slot in the ground. To achieve a good broadband,the antenna has an S-shaped slot in the radiation patch. A short adjustable branch is connect with the coupling feed to improve S parameter. The radiation patch is square-shaped with two triangle corners in an opposite direction . This millimeter antenna brings out a good circular polarization in two different frequency bands. The configuration of the antenna is simulated and optimized with Ansoft HFSS. Good characteristics of the antenna can meet the requirements of the radar tracking system and satellite communication. |
