【摘要】:針對傳統(tǒng)蘑菇陣列由于饋電點偏離中心導(dǎo)致的交叉極化增大等問題,本文提出了一種新型蘑菇形結(jié)構(gòu),并對其輻射特性進(jìn)行了研究。設(shè)計并制作了一款基于該新型蘑菇形結(jié)構(gòu)的2×2小型化全向天線,所設(shè)計的天線工作于2.27GHz,相對帶寬1.15%,交叉極化抑制度達(dá)到35d B,天線單元結(jié)構(gòu)的尺寸為0.15λ0×0.15λ0×0.01λ0,陣列結(jié)構(gòu)尺寸為0.3λ0×0.3λ0×0.01λ0,具有方位面內(nèi)的全向輻射方向圖且方位面的不圓度小于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.
