【摘要】 本文在圆形宽缝天线的基础上,通过加载径向金属条带的新结构,显著展宽了法向圆极化轴比的频带。借助仿真软件的参数扫描优选其结构初始值,用带约束条件的改进型多目标优化遗传算法结合仿真软件对天线结构进行优化设计,获得13.9%的1dB轴比和-10dB回波损失的公共频带。更多还原

【Abstract】 In this paper, the design of circular wide-slot antenna with radially loaded metal strips is presented for dramatically broadening the bandwidth of axial ratio (AR) along normal vector. The antenna structure is optimized by running a constrained multi-objective algorithm combined with simulation software, after determination of the initial parametric values by means of sweep simulation. An overlapped bandwidth of 13.9 % for 1 dB AR and -10 dB return loss is achieved by simulation.更多还原
