Abstract

In this paper, the design, optimization and simulation of a dual-band coaxial-fed H-slot microstrip patch antenna for WiMAX/WLAN application is presented. It operates on 3.6-3.7 GHz and 5.7-5.8 GHz bands. Radiating patch lies on the Teflon substrate which is having low dielectric constant. Coaxial feeding technique is used to feed the antenna with 50 ohm impedance. This proposed antenna enhances the return loss of -14 dB at the 3.65 GHz and -28 dB at 5.765 GHz frequencies. Computer simulated results showing the VSWR value lesser than two at the 3.6-3.7 GHz and 5.7-5.8 GHz frequency range of WLAN standards. It exhibits maximum gain of 8 dB at 3.65 GHz and 9 dB at 5.765 GHz.
