Wideband Planar Split Ring Resonator Based Metamaterials
By
Progress In Electromagnetics Research M, Vol. 28, 115-128, 2013
Abstract
In this paper, a method for increasing bandwidth of metamaterial structures is presented. The metamaterial structures used in this study are based on Split Ring Resonators (SRRs), the most recognized structures for realization of metamaterials with negative magnetic permeability coefficients. To increase the frequency bandwidth of such metamaterials, two different methods, 1) rotating the inner ring of SRR with different angles in a hybrid structure, which is herein called unit cell, 2) changing dimensions of SRR, are presented. Moreover, the effect of SRR arrangement in unit cell on bandwidth is investigated. The idea of bandwidth enhancement is verified via simulations, which are performed via full-wave method and measurements, which are done using a built strip-line setup.
