摘要

与中心馈电偶极子相比，非对称馈电线性辐射体通过大大降低地平线附近多径信号的严重程度来改善低角度卫星通信天线的性能。数值分析(NEC)和实测数据表明，通过增加上/下半空间能量比，特别是在接近地平线的区域，可以达到改善效果。

Asymmetrically fed linear antenna for low-angle VHF/UHF satellite communications

Compared with the center-fed dipole, an asymmetrically fed linear radiator is shown to offer improved low-angle, satellite communications antenna performance by greatly reducing the severity of the multipath signals near the horizon. Numerical analysis (NEC) and measured data show that the improvement is achieved by increasing the upper/lower half-space energy ratio, particularly in the region near the horizon.
