In this paper, we propose a novel UHF RFID coupled slot metallic tag antenna with a radome. The proposed tag antenna consists of a frequency tuning slot, imaginary part tuning slot, real part tuning stub, micro-chip, and radome. The RFID tag antenna was designed and fabricated for use in the Korean and Japanese UHF band of 916.7 to 923.5MHz. The measured 3dB frequency bandwidth is 914 to 926MHz. The measured read range is 11.5m on a metallic surface. Details of the proposed tag antenna design, as well as simulated and measured results are presented and discussed.
