Abstract

Design of a simple microstrip fed monopole patch antenna for the radio frequency identification (RFID) and wireless local area network (WLAN) is presented. The antenna has two different resonant paths (forming an F-shaped structure), supports two resonances at around 2.44 GHz and 5.18 GHz, which are reserved for RFID and WLAN applications. Effectively consistent radiation pattern and large impedance bandwidth has been observed. Impedance bandwidth for -10 dB return loss in the 2.44 GHz and 5.18 GHz center frequency reaches 0.65 GHz (2.12 GHz to 2.77 GHz) and 0.59 GHz (4.91 GHz to 5.50 GHz) respectively. The proposed antenna is simple and compact in size providing broadband impedance matching, consistent radiation pattern and appropriate gain characteristics in the RFID and WLAN frequency range.
