摘要

本文给出了分离元件尺寸对同轴x波段单极天线辐射特性影响的研究结果。特别详细地分析了单极子高度、地平面尺寸和单极子位置相对于地平面的变化。在时域有限差分模拟的基础上,表明了这些元件散射电磁场对辐射方向图形成的贡献。从而确定了峰值指向性的仰角变化规律。

Effect of finite screen and monopole's height on radiation characteristics of monopole antenna
This paper presents the investigation results on the effect of separate element dimensions on the radiation characteristics of coaxial X-band monopole antenna. In particular, the variations of monopole height, ground-plane dimensions, and monopole location relative to the ground plane are analyzed in details. Based on FDTD simulations a contribution of EM fields scattered by these elements in the radiation pattern formation has been shown. As a result, the regularities in the elevation angle of peak directivity changing have been determined.
