Abstract :
In this paper, a small RFID tag antenna in UHF band which has bandwidth-enhanced characteristic is proposed. The shape of the proposed antenna is a meander antenna to reduce size, and the antenna consists of two radiators which make dual resonance in adjacent frequencies to enhance bandwidth. By adjusting length and location of each radiator, the proposed antenna can easily make dual resonance at arbitrary location on the Smith chart, which is able to make impedance matching with RFID tag chip in wide frequency range
