说明：  设计一八木天线，振子数目为4，长度分别为：反射器长度0.39，主馈振子长度0.356，引向器长度均为0.3；反射器和主馈振子的距离0.265，主馈振子和第一引向器的距离0.2575，第一引向器和第二引向器的距离0.225。天线工作频率为400MHz，各振子分段数为9。 利用矩量法模拟该天线的电流分布，并绘制方向图。(A eight wood antenna is designed. The number of vibrators is 4 and the length is 0.39 for the reflector, 0.356 for the main feeder and 0.3 for the director. The distance between the reflector and the main feeder is 0.265, 0.2575 for the main feeder and the first director. The distance between the first director and the second director is 0.225. The working frequency of the antenna is 400MHz and the number of segments of each vibrator is 9.)
