Abstract: In the last few decades, the evolution in new-fashioned wireless communication systems has actuated augmented exploration on uncomplicated dual band antennas. In this paper, a dual-band half psi shaped antenna for WLAN, Wi-Fi and WiMAX appliances is designed and analyzed. The intended antenna constitutes a half psi shaped radiating patch on the cost effective FR4-substrate with 1.6 mm thickness. A 50 ohms feed line is employed to feed half psi shaped antenna. Here a preferable impedance matching is attained by truncating a portion of the ground surface. The intended antenna has the potential to resonate between the frequency bands of 1.88 GHz-2.75 GHz and 5.17 GHz-5.74 GHz with S11 below -10 dB. The design of the antenna and its behavior over various frequencies ranges is done with the use of HFSS. The proposed antenna has higher gains at two regions. The simulated antenna is also prototyped and a fine similarity is attained in between the simulated parameters and measured parameters.
