摘要
Abstract
A new method to optimize the array antenna directional pattern is proposed,in which the cell antenna array is simulated with Ansoft HFSS software to extract the current data or far⁃field data of each exclusive feed cell,and then the genetic algorithm(GA)is used to optimize the extracted current data to obtain the cell current value and phase value satisfying the re⁃quirement of directional pattern. The method can conveniently synthesize the antenna array directional pattern with arbitrary charac⁃teristics due to the flexible HFSS modeling,and only a simple far⁃field extrapolation or superposition for the extracted data is needed while optimizing,so it has fast calculation speed. Different from the traditional optimization method using GA only,the method combining engineering software Ansoft HFSS with GA can effectively improve the computational accuracy of the antenna array synthesis,computational efficiency of the objective function,and the optimization efficiency of the directional pattern.关键词
