摘要: 本文设计了一种应用于卫星定位系统的微带天线,具有较大的波束宽度和较好的圆极化特性。该天线采用了接地板开槽的微带天线和角锥喇叭结构:在接地板上开槽引入几何微扰,实现了圆极化;将接地板开槽的微带天线安置于角锥喇叭之上,达到了展宽波束的目的。仿真结果表明,该天线在E面和H面形成了宽波束,E面波束宽度大于123°,H面波束宽度大于136°,而且在波束范围内都有很好的圆极化特性。
Abstract: The paper presents a microstrip antenna applied to global positioning system(GPS),have a greater beam width and good circular polarization characteristics. The slotted ground plane microstrip antenna and pyramidal horn structure are adopted,the ground plane embedded slots can excite circularly polarized(CP)radiation,then slotted ground plane microstrip antenna placed on the pyramidal horn structure can reached a wide-beam. The simulation results show that the antenna in the E plane and H plane to get wide beams,E plane beam width is greater than 123 °,and H plane beam width is greater than 136 °,while the circular polarization characteristics are remarkable within the beam width.
