Metamaterial Inspired Gain Enhanced Elliptical Curved CPW fed Multiband Antenna for Medical and Wireless Communication Applications

Abstract

This article presents a novel elliptical curved coplanar waveguide fed antenna with defected ground. Electromagnetic coupling between splitring resonator (SRR) on other side to the substrate to CPW feeding line on the top side resulting the frequency notches in the wideband. The SRR shaped etched portion in the ground plane not only miniaturizing the antenna, but also providing good bandwidth in the operating bands. Antenna providing multiband characteristics for PCS, Bluetooth, LTE, ISM (Medical Application Band) and Wi-Fi communication (2-3.6 GHz), WLAN IEEE 802.11a/h/j/n (4.5-5.825 GHz), satellite system X-band downlink (7.5-9 GHz) and satellite communication applications at (12-16 GHz) & (17.5-18.5 GHz) respectively. This antenna offering quad band notching with penta band operation from 2-20 GHz. The size of the antenna is 40X44X1.6 mm with peak gain value of 7.18 dB with average efficiency parameter more than 68%. The manufactured antenna prototype is tested for validation and the obtained measurement matching with respect to the optimized simulation result.
