Abstract

This paper introduces a new low cost, robust microstrip structure, exhibiting metamaterial property, as a replacement of conventional bulky metamaterials structures. These types of planar microstrip structures are very useful for applications where space of equipment is a constraint. Although, the structure is inspired by Split-Ring resonator (SRR), it does not incorporate additional metallic rod for electrical resonance, as used with conventional SRRs. The rings are elliptical in shape and coaxial dual feeding has been used that are offset in phase. Simulations of the elliptical split ring resonator (ESRR) have been carried out in microwave regime. S-parameter simulation results of the resonator show metamaterial property at multiple frequency bands.

Key words: Metamaterial, microstrip structures, split ring resonator, negative refractive index material, microwave.
