Abstract :
A novel broadband UHF RFID tag antenna mountable on metallic surface is proposed. The structure consists of a feed loop with two short stubs and two symmetrical radiating patches shorted to ground plane. The proposed antenna has an impedance bandwidth of 8% within 858-929 MHz for the reflection coefficient to be below -7.36 dB (VSWR < 2.5). Additionally, the proposed antenna shows a good performance when mounted on the metallic objects.
