| 摘 要： | 介绍了一种新型的Ku频段宽带高增益双极化微带贴片单元及96元阵列的设计。设计中单元采用层叠贴片天线结构,提高了单元的带宽和增益,两个极化端口采用分层馈电,其中水平极化端口采用共面馈电,垂直极化端口采用探针背馈。在馈电网络的设计中引入反向馈电技术,降低了交叉极化。仿真与实测结果表明:该阵列增益达到了26dBi,口径效率约为51%,交叉极化电平小于-30dB,水平极化端口相对阻抗带宽达11.3%,垂直极化端口相对阻抗带宽达13.7%,两端口隔离度高于40dB.

| Abstract: | In this paper,a novel design of dual-polarized microstrip patch element and 96-element array with wide bandwidth and high gain is proposed for Ku-band application.A stacked patch antenna(SPA) architecture is adopted in the element design in order to increase the bandwidth and gain.Dual-layered feeding technique is used to achieve the dual-polarization,where the horizontal polarization port is fed with a coplanar microstrip line,while the vertical polarization port is excited by a probe.The anti-phase feedin... |
