Abstract: An Ultra High Frequency (UHF) half-loop antenna used in Radio Frequency Identification (RFID) systems is proposed with a planar patterned metamaterial structure of compact size. The size of the planar patterned metamaterial structure is (0.20λ*0.20λ*0.0023λ') mm3. This antenna consists of two metamaterial unit cells having negative permittivity and permeability. Simulation results of input return loss, radiation pattern, and directivity of this antenna are presented using CST software. A comparison between the conventional antenna and the new metamaterial half-loop antenna is also provided. The simulated results show that the metamaterial antenna has a resonance frequency of 0.866 GHz, a realized gain of 1.96 dB, and an efficiency increase of about 20%. Simulation and measurement results are in perfect agreement, which proves that the proposed antenna can operate in the UHF band for RFID systems.
