Abstract :
Micro strip patch antennas are strong candidates for use in many wireless communications applications. In this paper, the design, optimization and simulation of a dual-band modified U-slot micro strip patch antenna for WiMAX/WLAN application is presented. It operates on 2.45-2.57 GHz and 5.1-5.4 GHz bands. Radiating patch lies on the Rogers RT/duroid 5880 substrate which is having low dielectric constant of 2.2. Coaxial feeding technique is used to feed the antenna with 50 ohm impedance. This proposed antenna enhances the return loss of -19.5 dB at the 2.5 GHz and -30 dB at 5.27 GHz frequencies. Computer simulated results showing the VSWR value lesser than 2 at the 2.45-2.57 GHz and 5.1-5.4 GHz frequency range of WLAN standards. It exhibits maximum gain of 6.15 dB at 2.5 GHz and 9.1 dB at 5.27 GHz.
