In this paper, we presented RFID multi-band reader antenna design that is worked in four UHF standard bands to cover all around the world RFID classification frequencies. 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. A multiband compact RFID antenna design for inductive and capacitive near- and far-field UHF and 2.4 GHz is presented. The fabricated antenna works at 890 to 933 MHz, 1.57 (GPS-L1), and 2.4 GHz.
