Metamaterials inspired dual-wide band CPW-fed antenna using split ring resonator structure

Abstract

This paper presents a metamaterial inspired dual-wide band CPW-fed antenna using split-ring resonator structure. The antenna design is inspired from conventional circular monopole antenna to two split rings resonators. The antenna geometry is optimized to achieve two wide bands; the lower band covers the band 2.65 GHz to 3.25 GHz where the higher band covers the band 5 GHz to 7 GHz. The antenna dimensions are optimized for compact size (30 mm × 30 mm). The antenna radiation pattern is kept as Omni-directional in both bands. Full wave simulation and experimental measurements results are introduced with good matching between them.
