A New Design of a Compact Metamaterial Antenna for RFID Handheld Applications

The development of miniature antennas is the key requirement for radio frequency identification applications in various fields.  In this paper, a new design of a compact metamaterial microstrip antenna based CSRR resonators is proposed. The proposed metamaterial antenna has a simple structure. It is formed by a rectangular patch embedded a T-shaped slot in one side, and a two metamaterial unit cells formed by CSRR etched from the ground plane in the other side. The designed antenna is printed on an epoxy Frame Resistant ۴ substrate by using CST Microwave Studio. It operates at two RFID bands around ۵.۸GHz and ۲.۴۵GHz. The designed antenna is fabricated by using an LPKF machine. The simulation results have been justified by measuring the parameters, respectively.
