Synthesis of Antenna Arrays Using Genetic Algorithm

摘要: 该文采用了两种基于遗传算法的方法对线阵列天线进行了综合。仿真结果表明，这两种方法均能够逼近Chebyshev综合的结果。与Chebyshev法相比，具有灵活性强，不受天线工作频率限制等优点。其中第二种方法将遗传算法与Schelkunoff法结合起来，能够方便精确地在指定位置得到零点并满足其它的优化条件。Abstract: In this paper, two methods for the synthesis of the pattern of a linear array, based on Genetic Algorithm(GA), are discussed. The results of the two methods can all ap proximate the results of the Chebyshevs method. Compared with the method of Chebyshev, the two methods using GA have more flexibility and have no restriction on the frequency of the antenna. By using the second method which combines Schelkunoffs method with GA, arbitrary locations of nulls can be got in the pattern with other optimizing conditions.
