Abstract
In this paper a shorted U-shaped patch antenna fed by another patch on the same layer is proposedfor the dual GSM band operation.The U-shaped patch is fed by electromagnetic coupling by another coaxially fed patch on the same layer,which operates at the higher frequency band.For the GPS operation an upper layer is used with a rectangular patch.In this paper Simple Genetic Algorithm (SGA) and Divided Rectangles technique (DIRECT) global search algorithm are used to searchfor the optimal antenna geometry.The two algorithms are introduced and compared.
摘要
本文中,假定有一种由同一层面上的另一贴片馈电的压缩的U型贴片天线用于双向的全球移动通信系统.这种U型贴片由同一层面上的同轴馈电贴片以 电磁连接的方式馈电,该同轴馈电贴片凭高频传送带操纵.上层有一直角贴片用以操作全球定位系统的运行.本文运用了简单基因算法和矩形分割技术全球搜索运算以寻求最佳天线几何.两种算法被引入并加以比较.
