Abstract :
A novel multiband microstrip patch antenna is introduced and antenna performances are optimized, simulated and analyzed. Comparative analysis is shown in between a common patch antenna and a suspended patch antenna. The proposed antenna is designed to function in the various multiple bands ranging from 1-6 GHz covering wide range of applications such as GPS, Wi-Fi, Bluetooth, Zigbee and ISM band applications. It achieves multi-band functionality when PBG (photonic band gaps) of radius 10mm and height 1.5875mm, in substrate are introduced at proper places in the substrate. A rectangular patch (37.2mm by 23.34mm by 0.01mm) is used. At each band, obtained corresponding VSWR is near to 1. The proposed antenna provides good return loss Sll and impedance behavior and reduces surface waves. Far-field radiation pattern and field distributions on the coaxial probe feed patch have been analyzed.
