摘　　要：针对中小渔船雷达天线的需求,提出了一种适用于X波段的圆极化船舶雷达微带天线。为了增加天线的辐射方向性、减小天线的尺寸并降低天线的复杂度,将20辐射单元交错位于馈电网络两侧;与贴片边缘相连的阻抗变换器采用蜿蜒型结构;馈电网络采用阶梯型阻抗变换器。设计的天线实物长度约26 cm,其工作中心频率在9.3 GHz,测试结果表明,该天线具有良好的定向性和圆极化性。Based on the requirement of radar antenna for small and medium fishing boats,an X-band circularly polarized micro-strip antenna for marine radar is put forward.In order to increase the radiation direction of the antenna,reduce the size of the antenna and reduce the complexity of the antenna,20 radiating elements are interlaced on both sides of the feed network,a meander structure is applied to the impedance converter connected to the edge of the patch,and a staircase impedance converter is used in the feed network.Finally an antenna is designed,with a length about 26 cm and a working center frequency at 9.3 GHz.Test results show that the antenna has good directivity and good circular polarization.
