Dual-Band Parasitic Microstrip Patch Antenna for Wireless Applications

Abstract

The paper presents a novel dual-band patch working at GSM band and S-band. The patch encompasses a rectangular radiator coupled with a parasitic patch in the coplanar region and a split ring resonator in the ground region. The patch is analyzed numerically and is synthesized using the HFSS simulator. Finally, the performance characteristics of the model are measured and are compared with numerical and simulated results. The patch gives two different bands at 950MHz and 2.3GHz and gives -10dB impedance bandwidth in the lower band from 950MHz -1GHz and higher band from 2.275GHz – 2.325GHz. The patch also accomplishes a gain of 4.74dBi in the effective band 1 and 4.02 dBi in the operating band 2.
