采用耦合Hallen方程分析八木天线

Analysis of Yagi Antenna Using Coupled Hallen Equations

八木天线是一种常用的天线形式,采用了二元偶极子模型的耦合方程,并结合矩量法Hallen方程分域基分析了八木天线的数值计算方法。运用此方法,充分考虑了阵元间的互耦效应,而且计算起来比较简便,并降低了矩阵维数。仿真设计了一个三元八木天线,计算结果与传统方法比较,表明了此方法准确有效。

Yagi antenna is a common form of antennas,according to the coupled Hallen-Pocklington equation of the model of two-element dipole array,the numerical method of the Yagi antenna is analyzed combined with MoM.The analysis methods consider the coupled effect and simplifiy the calculating expression,diminish the dimension of the matrix.A three-element Yagi antenna is designed using the method,and compare with the conform method.which presents the method is precise and efficient.
