Abstract

Design of a simple microstrip fed monopole patch antenna for the radio frequency identification (RFID) is presented. The antenna has two different resonant paths (forming an inverted double L-shaped structure), supports two resonances around 2.41 GHz and 5.85 GHz, which are reserved for RFID applications. Effectively consistent radiation pattern and large impedance bandwidth has been observed. Impedance bandwidth for -10 dB return loss in the 2.41 GHz and 5.85 GHz center frequency reaches 0.97 GHz (1.95 GHz to 2.92 GHz) and 1.51 GHz (5.23 GHz to 6.74 GHz) respectively.
