Abstract :
Methods to implement RFID tag antenna´s complex impedance been discussed, the results show inductively coupled rectangle ring feeding structure is an convenient way to implement complex impedance. A UHF band inductively coupled ring feeding RFID tag antenna is proposed, meanwhile, the dimension parameters´ influence on antenna´s impedance is studied. This antenna shows S11<;-10dB bandwidth as 880~960MHz, gain as 2dBi while its dimension as 90mm ×16mm. The measured result s are compared with the simulated results, and good agreement is obtained.
