In this paper, a new proposed design is presented for UHF RFID antenna matched to the Moroccan frequency band authorized by the ANRT. A proposed structure is inspired from circular split ring resonator theory, the geometry of the RFID antenna is double sided. Front side presenting a modified SRR while the back side is a circular ground plane. In order to achieve a good matching input impedance between the antenna and the impedance of the UHF chip, the structure is combined a modified SSR with stubs. The EM simulation of the proposed antenna done by EM Solver on an FR-4 substrate. The use of SRR permit to obtain good results of simulation with a reflection coefficient about-26,146dB at the Moroccan frequency band around 868MHz , a good read range and reduced size of RFID antenna were obtained with physical dimensions of 32×18×0.87 3 which presents 62.9% in comparaison with diemnsions of λ/4 length.
