大垂直口径天线俯仰波束赋形设计
内容简介:给出了一种大垂直口径天线俯仰波束的优化设计过程.大垂直口径天线由10个辐射阵元构成,可以看成为一个阵列.为使天线的辐射波束达到给定的波束要求,提出了一种改进的遗传算法及其目标函数模型,对各辐射阵元的馈电幅度和相位同时进行优化.计算结果显示,天线能够产生满足设计要求的俯仰波束.通过全波电磁仿真软件HFSS进行了验证,仿真结果与计算结果吻合,证明了所提方法的有效性和实用性.
Abstract:@@@@Optimization and design process for shaped elevation beam of a large vertical aperture( LVA) antenna is presented . The LVA antenna consists of 10 radiation elements . In order to form a given antenna pattern for LVA antenna, an improved genetic algorithm(GA) and its weight objective function model are proposed, which are applied to optimize the amplitudes and phases of the currents of the radiating elements . Calculated result shows that the elevation radiation pattern meets the design requirement . The simulated result by using full
