行波电流天线阵的加载

On the Loading of Array Elements for Travelinhg-Wave Currents

天线进行加载后可使电流以行波分布，从而改善天线的综合性能。本文以两单元天线阵为基础讨论天线阵的行波加载问题，提出了确定阵单元加载量的加载公式。研究了加载量与相关参量的相互关系。数值计算表明，天线阵经加载后可保证在全方位的电扫描过程中，保持单元电流的行波分布，从而可使天线阵的系统性能得以改善。另外所导公式计算简便，避免了传统方法解决同类问题时计算量大的困难。

A traveling-wave distribution of current can be produced on a convetional linear antenna,such as a dipole,through resistive loading.The present paper concers with the loadings of paralles traveling-wave linear antennas.The formulas are proposed to determine the antenna loading with impedance orresistance.The relationnships between the loading and other parameters are discussed as well. Numericalcalculation show that the deduced formula is dependable,and puite simple for computation.
