Abstract :
A simple tag antenna for the Korean ultra-high-frequency radio frequency identification (RFID) band (908-914-MHz) using a modified dipole structure is proposed. The overall dimension of the tag antenna is 64.1 times 17.8-mm. The input impedance of the designed tag antenna is 43-j800 Omegaand is conjugately matched to a Philips EPC UCODE Gen 2 RFID tag microchip with an impedance of 43-j800 Omega at 912 MHz. Good wake-up sensitivity and radiation pattern characteristics were obtained in the desired frequency band.
