More Information
Summary:The present disclosure relates to an RFID tag, more particularly to, a UHF band RFID tag antenna using a double-open ends coupler; wherein the structure thereof is using a half wavelength dipole antenna with a double-open ends coupler mutually coupled to each other, and the RFID chip is disposed upon the coupler, and the coupler is designed to be double-open ends structure so as to, rather than prior arts, enhance the radiation without compromising the impedance match between the antenna and the chip.
