Summary:
This paper presents a new design of a dual-frequency circular patch antenna for RFID reader application. The dual-frequency is achieved by employing slot loading and meandering slits. By appropriately inserting the positions of slots and slits, the proposed RFID antenna exhibits dual operating frequencies at both the UHF band ranging from 850 MHz to 891 MHz and the microwave band frequency ranging from 2.44 GHz to 2.48 GHz. More importantly, it results in the size reduction for dual-frequency operation. The return loss and radiation pattern of the proposed antenna are presented.
