Abstract :
A printed dipole antenna for UHF band RFID tag is proposed. With both meander line loaded and parasitical element loaded technology, this tag antenna and ASIC chip realize impedance match around resonant frequency, which assures maximum power transmitting in RFID system, especially important for passive tags. The impedance bandwidth reaches to 18.9%, and H-plane is omnidirectional with a maximum gain of 1.038 dB.
