大张角对数周期天线的宽带特性
内容简介:本文采用矩量法分析和计算了对数周期天线在张角较大时,它的阻抗、电压驻波比、增益及方向图的宽带特性,讨论了这些特性与天线结构参数之间的关系.根据分析和计算,设计并制作天线进行实验测试,理论计算和测试结果表明,两者吻合较好.
Abstract:The method of moments is used to analyze and calculate the broadband characters of impedance,voltage satanding wave ratio(VSWR),gain and radiation pattern of larger angle LPDA,and the relation between these characters and the parameter of antenna construction is discussed in this paper.Based on analysis and calculation,the antenna is designed and tested,and the measured results are in good agreement with the theoretical calculation.
