IC卡读写器用的一种四元振子天线分析

Analysis of Dipole Antenna Array Using in IC Card Reader

介绍用于IC卡读写器系统中一个天线阵的实际例子 ,天线由四单元半波振子组成 ,振子之间为平行双线馈电 ,通过同轴电缆接到直立的平行双线 ,在阵列几何中心向阵列两侧馈电 (并馈 ) ,分析了带有接地板的天线方向图及其随激励的变化 。

This article analyses an example of dipole antenna array using in IC card reader.The antenna is composed of four half-wave dipole antenna units.Four units are feeded from the geometry center of antenna array.The simulation result of antenna pattern taking into account ground is compared as it's feeded different phases.Finally experiment result of VSWR is given.
