本文介绍了一种用于增加圆偏振（CP）辐射束宽的技术。采用金字塔形接地结构和部分封闭的平面导电墙，设计的CP贴片天线高度仅为0.121，3dB轴比波束宽度大于130 °。工作在1575 MHz的GPS频段的实验结果，并进行了讨论。
This paper presents a technique developed for increasing the beam width of the circularly polarised (CP) radiation. With a pyramidal ground structure and a partially enclosed flat conducting wall adopted the designed CP patch antenna has a height of about 0.121 only and exhibits a 3 dB axial-ratio beamwidth of more than 130deg. The experimental results for operating in the 1575 MHz GPS band are presented and discussed.
