Design of Microstrip Patch Antenna with Enhanced Bandwidth and Harmonic Suppression for Wlan Applications

Abstract

A parallel combination of pair of λ/4 Resonator and the rectangular patch has enhanced the bandwidth and suppressed the unwanted harmonic radiations of the proposed antenna. Due to electromagnetic coupling effect, the pair of λ/4 resonator excites the radiating patch. Both λ/4 resonator and resonating patch excites at two different frequencies which are close to each other and this helps to increase the bandwidth of a proposed antenna. Also a shorting pin is used between the two λ/4 resonators which suppress the unwanted harmonic radiations. Design of a proposed antenna is done using the HFSS (High Frequency Simulation software). The Hardware results are observed on VNA (Virtual Network Analyzer).The operating frequency 3.6GHz.The proposed antenna is used in WLAN applicatio
