Abstract

A novel compact microstrip antenna is presented for tri-band RFID applications.The antenna consisting of a monopole like bent arm with a capacitively coupled small patch, printed on the alternative side of the ground plane, which might be common for multi-layer reader circuitry. By adjusting the dimension of the bent arm as well as the embedded bent and capacitive coupling, tri-band antenna has obtained in a small profile. The prototyped antenna shows broad impedance bandwidths (10 dB ≤ return loss) of 17.5, 32.7, and 25.5% accordingly in UHF (902-928MHz), 2.45GHz and 5.8GHz RFID bands with stable radiation characteristics.
