【摘要】：针对传统蘑菇阵列由于馈电点偏离中心导致的交叉极化增大等问题,本文提出了一种新型蘑菇形结构,并对其辐射特性进行了研究。设计并制作了一款基于该新型蘑菇形结构的2×2小型化全向天线,所设计的天线工作于2.27GHz,相对带宽1.15%,交叉极化抑制度达到35d B,天线单元结构的尺寸为0.15λ0×0.15λ0×0.01λ0,阵列结构尺寸为0.3λ0×0.3λ0×0.01λ0,具有方位面内的全向辐射方向图且方位面的不圆度小于0.15d B。
[Abstract]:In view of the cross polarization caused by the deviation of the feed point from the center of the traditional mushroom array, a new mushroom shape structure is proposed and its radiation characteristics are studied. A 2 x 2 miniaturized omnidirectional antenna based on the new mushroom structure is designed and produced. The antenna is designed to work at 2.27GHz, and the relative bandwidth is 1. .15%, the cross polarization suppression reaches 35d B, the antenna element structure size is 0.15 lambda 0 x 0.15 lambda 0 x 0.01 lambda 0, the array structure size is 0.3 lambda 0 x 0.3 lambda 0 x 0.01 lambda, has the omnidirectional radiation pattern in the azimuth surface and the azimuth surface is less than 0.15d B.
