Abstract

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.
