针对全向天线高性能的要求,提出了一种并行馈电的天线阵列方案并完成设计。天线设计采用了三扇区合成全向覆盖的方案。通过改变寄生单元的负载,调整扇区天线波束宽度,使之满足扇区天线的-6dB波束为120°的要求.有效的减小了天线在水平面的波动性。实际测试表明该天线具有高增益,良好的全向性,达到了设计要求。
針對全嚮天線高性能的要求,提齣瞭一種併行饋電的天線陣列方案併完成設計。天線設計採用瞭三扇區閤成全嚮覆蓋的方案。通過改變寄生單元的負載,調整扇區天線波束寬度,使之滿足扇區天線的-6dB波束為120°的要求.有效的減小瞭天線在水平麵的波動性。實際測試錶明該天線具有高增益,良好的全嚮性,達到瞭設計要求。

In order to achieve an ideal omni-directional pattern,a parallel feed patch antenna array is designed. The antenna consists of three parallel feed patch antenna arrays which are arranged in triangular configuration.. By changing the loading resistors of the parasitic elements, the -6 dB beam width of sector antenna can be adjusted to 120°, and the fluctuation of the composite pattern can be suppressed in horizontal plane. The experiments show that this antenna has good performance, and achieve the design requirement.
