Multiband Antenna For RFID Application

Abstract

This paper presents a multiband planar antenna design for RFID applications. The proposed antenna is working for five useful bands: 2.45GHz, 3.22GHz,3.61GHz, 4.42GHz and 5.52GHz. The gain of the antenna at these frequencies are -2.89dB,-16.2 dB,-4.9dB,-2.42dB and -0.12dB respectively. Simulated results are agreed well with the measured results. The antenna is fabricated on low-cost substrate FR4and its dimensions are $40 \times 55 \times 1.6$ mm3.
