In this paper, the authors present a microstrip patch antenna with diagonally symmetrical slots for RFID applications. The unequal length center cross slot with four circular slots on its diagonal axes are embedded onto the square patch radiator. These slots are introduced to achieve compact size and this antenna is designed for UHF RFID handheld reader applications. The coaxial feed is used to excite the proposed antenna. The 10dB return loss bandwidth and VSWR of proposed antenna are 15.3MHz (917.7-933) and 0.5 respectively.
