Design of Rectangular Patch Antenna by using an artificial planar meta-surface for Mobile RFID Reader

Abstract

In this paper, a meta-surface based on a rectangular microstrip patch antenna for mobile RFID reader applications is presented, the meta-surface structure consists of a magneto-dielectric split ring resonators with high permeability material (μeff= 8.07+j3.01) at 2.44 GHz, which is placed on the patch antenna.The use of the proposed modified double rectangular slot ring resonator (MDRsRR) with 6x6 array increases the gain of the proposed antenna up to 4.28 dB. The obtained results of this proposed antenna proves that it’s a good antenna in terms of gain, return loss (S11), and adaptation.
