Modified dual monopole antenna for WLAN operation

Abstract

Abstract A novel and simple design of a coplanar waveguide‐fed folded dual monopole antenna with dual‐band frequency operation for a wireless local area network (WLAN) application is proposed. The obtained impedance bandwidths reach about 37.3% for the 2.4 GHz and 15.5% for the 5.8 GHz band, meeting the required bandwidth specifications of the IEEE 802.11a/b/g standards. The peak antenna gains for the operating frequencies across dual WLAN bands are measured to be 6.30 and 5.16 dBi, respectively. © 2011 Wiley Periodicals, Inc.
