Design and FDTD analysis of single-band and dual-band antennas for RFID and WiMAX applications

In this paper, inset fed microstrip antennas for single band and dual-band operation are proposed. This design aims to achieve single band operation for RFID at 2.4 GHz as well as dual-band operation at 2.4 GHz for RFID and 3.5GHz for WiMAX applications. Simulation results exhibit a return loss of -27dB for single-band operation (2.4 GHz) while at and -20dB and -12.87dB for 2.4GHz and 3.5GHz (for dual-band) respectively. The Finite Difference Time Domain (FDTD) technique was used to analyze both antennas showing close agreement with the simulated results.
