风载荷对垂直对数周期天线电气性能影响分析

摘要

基于矩量法，分析了软结构垂直对数周期天线在风载荷作用下的性能。并结合工程实际对该种软结构天线在风载荷下的阻抗特性、方向特性进行了详细计算。论文的结果对相控阵天线、测向天线等对稳定性、一致性等要求较高的天线阵列选型、设计具有一定的参考意义。%Based on the method of moments ,the performance of the vertical log periodic antenna under wind load is an‐alyzed .A detailed calculation of the antenna's impedance characteristics and directional characteristics under wind load is car‐ried on .The data drawn from the calculation is of reference in the array and design of high stability and consistency modes of antenna ,such as phased‐array antennas and direction‐finding antennas .
