Abstract :
A novel and simple antenna, which is designed for active RFID tags at 2.45 GHz, is proposed. The antenna, consisting of a short rectangle dipole and a bent ´T´ shape monopole, is suitable for direct integration with electronic components such as batteries without significant antenna performance degeneration. Simulation and measurement results show that the proposed antenna provides good gain, excellent bandwidth and omndirectional radiation pattern.
