本文提出了一种新颖的圆极化4天线阵列结构及其扩展到16天线阵列的方法。首先给出了单天线和由S型走线馈电的正交排列的4天线阵列的新颖配置。人们发现S型走线具有最小化和消除平行馈线两侧之间相互反射的能力。然后，由上述设置在四个象限上的4天线阵列得到16天线阵列。天线阵列外围的接地环可消除横截面辐射。所提出的天线阵列的特性通过 3D 计算机仿真给出。首次实现极宽带轴比，带宽是传统平面天线的10倍。
This paper presents a novel structure of circularly polarized 4-antenna array and its expansion to 16-antenna array. First a novel configurations are given of a single antenna and a 4-antenna array with orthogonal arrangement fed by S-type routing wire. S-type routing wire was found to have capabilities of minimizing and cancelling reflections mutually between both sides of parallel feeding lines. Then, 16-antenna array is given by the above 4-antenna array settled on four quadrants. Grounded collars at the peripherals of antenna arrays operate to eliminate cross-sectional radiations. The characteristics of the proposed antenna array are given by 3D computer simulation. Extremely wideband axis ratio was first realized with 10 times wide bandwidth compared to conventional plane antennas.
