Abstract

The design of a simple microstrip fed folded strip monopole antenna (FSMA) with a protruding stub in the ground plane for the application in WLAN and RFID is presented.The antenna has two resonant paths, one in the radiating element (folded strip) and the other in the protruding stub of the ground plane.It supports two resonances at 2.4 GHz and 5.81 GHz, which are the center frequencies of WLAN and RFID.Effectively consistent radiation pattern and large percentage bandwidth have been observed.The measured percentage fractional bandwidth at 2.4 GHz (2.05 GHz to 2.86 GHz) is 32.99, and the percentage fractional bandwidth at 5.81 GHz (5.55 GHz to 6.14 GHz) is 10.11.The proposed antenna is simple and compact in size, providing broadband impedance matching, consistent radiation pattern and appropriate gain characteristics in the WLAN and RFID frequency regions.
