Abstract

This paper presents the slot antenna fed by microstrip line with inset U-strip for dual frequency operates in WLAN applications. The rectangular slot antenna is proposed for comparison between with and without U-strip in slot antenna by using three configurations of slot antenna. This antenna is designed for dual frequency used in WLAN system coverage IEEE 802.11 b/g (2.4-2.4835 GHz), IEEE 802.11j (4.90-5.091), IEEE 802.11a (5.15-5.35 GHz) and WiMAX of IEEE802.16d (5.7-5.9 GHz). The PCB-FR4 substrate with dielectric constant (epsiv_r) 4.5 of thickness 1.6 mm is chose for low cost. The simulation results of these slot antennas are analyzed by using Method of Moment (MoM) from IE3D Software. Finally, the result of bandwidth at low frequency and high frequency of the desirable antenna are 9.76% and 31.6% at frequency range 2.3-2.58 GHz and 4.76-6.34 GHz, respectively.
