Abstract


A novel design for miniaturization of microstrip patch antenna for the RFID reader is proposed. The proposed antenna design consists of two L-shaped slots on the patch and two parallel slots on the ground plane. The patch and the ground are shorted through a shorting probe. The area of the proposed antenna is reduced around 51% compared with the slot less one. The validity and feasibility of the proposed antenna has been simulated and analyzed by HFSS. The simulation results show that the proposed antenna has relatively good gain of 8.05dBi and radiation characteristics and it covers the required bandwidth, 902-928MHz. The measured results are compared with the simulated results, and good agreement is obtained.
