Design of a simple microstrip fed folded strip monopole antenna with a protruding stub in the ground plane for the application in the WLAN and RFID is presented. The antenna has two resonant paths, one in the radiating element (folded strip) and other in the protruding stub in the ground plane, supports two resonances at 2.41 GHz and 5.82 GHz, which are the center frequencies of the WLAN and RFID. Effectively consistent radiation pattern and large percentage bandwidth has been observed. The percentage bandwidth at 2.41 GHz (2.07 GHz to 2.84 GHz) is 32.98 and the percentage bandwidth at 5.82 GHz (5.54 GHz to 6.14 GHz) is 10.13. The proposed antenna is simple and compact in size providing broadband impedance matching, consistent radiation pattern and appropriate gain characteristics in the RFID frequency range.
