摘要

本文研究了当RFID标签天线水平放置在金属板附近时，金属板对天线参数(输入阻抗、回波损耗和辐射方向图)的影响。金属板具有有限的尺寸和矩形形状。采用Ghannay等人提出的基于矩量法和RWG基函数的新技术，模拟天线参数对板的尺寸和天线与板之间距离的依赖关系。

Effects of metal plate to RFID tag antenna parameters

In this paper, the effects of a metal plate to antenna parameters (input impedance, return loss and radiation patterns) is presented when the RFID tag antenna is horizontally placed near the metal plate. The metal plate has finite size and rectangular shape. The new technique based on the moment method and RWG basis functions developed by Ghannay et al. has been used to simulate the dependency of antenna parameters on the size of the plate and the distance between the antenna and the plate.
