A dual band CoPlanar Waveguide (CPW)-fed planar monopole antenna suitable for WLAN (Wireless Local Area Network) application is presented in this paper. The antenna resembling as a "G" shape and optimally designed by using the Particle Swarm Optimization (PSO) algorithm can produce dual resonant modes and a much wider impedance bandwidth for the higher band. Prototypes of the obtained optimized antenna have been constructed and tested. The measured results explore good dualband operation with -10dB impedance bandwidths of 9.7% and 62.8% at bands of 2.43 and 4.3GHz, respectively, which cover the 2.4/5.2/5.8GHz WLAN operating bands and show good agreement with the numerical prediction.
