Research and Implementation of Software Package for Analysis Microstrip Antenna with Finite Base Plate

开发了一款用于有限大底板微带天线计算的软件包.利用矩量法对微带天线进行三角形和四面体剖分,将阻抗矩阵分为导体对导体作用、导体对介质作用、介质对导体作用和介质对介质作用的4类阻抗矩阵;通过计算4类阻抗矩阵,求得电流系数,完成对天线性能的分析;最后基于矩阵实验室编程环境,实现软件包.通过与FEKO软件的仿真结果对比表明,该软件包操作简单、可视性强、计算精度较高,可用于有限大底板微带天线的分析和计算.

A software package for the calculation of microstrip antenna with finite base plate is developed.The microtrip antenna is partitioned into triangle and tetrahedron using moment method.The impedance matrix is divided into four types:conductor-to-conductor,conductor-to-medium,medium-to-conductor and medium-to-medium.By calculating the four types of impedance matrix,the current coefficient is obtained and the performance of the antenna is analyzed.Finally,the software package is implemented based on matrix laboratory(MATLAB)programming environment.Compared with the simulation results of FEKO software,the software package has the advantages of simple operation,high visibility and high calculation accuracy.It can be used for the analysis and calculation of microstrip antenna with finite base plate.
