Abstract

UHF-band radio frequency identification (RFID) antenna for mobile handset applications is presented. The proposed antenna consists of a radiating element and a parasitic element connected to the ground plane. The radiation pattern of proposed antenna is orthogonal to that of a monopole antenna. The impedance bandwidth (902 MHz ~ 923 MHz) covers a Korea mobile RFID service (908.55 MHz ~ 913.95 MHz). The measured antenna peak gain is -0.37 dBi at 911 MHz.
