초록
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 64.1x17.8 mm. The input impedance of the designed tag antenna is 43+j800 Omega and 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.
