Abstract: This paper presents a compact multiband microstrip patch antenna for RFID applications which resonates at 912 MHz and 5.8 GHz. The multi-frequency behavior is obtained by etching four asymmetric square-shaped slots and slits in the patch. Coaxial feeding technique is used to design this antenna. The design is simulated using Computer Simulation Technology (CST) Microwave Studio software. Finally, the results obtained from the simulations are demonstrated.
