Abstract :
A resonant-type balanced composite right/left-handed (CRLH) coplanar waveguide (CPW) structure based on split ring resonators (SRRs) is presented. An equivalent circuit model is used to describe its complicated behaviour. As the higher cutoff frequency of the left- handed (LH) band and the lower cutoff frequency of the right- handed (RH) band are identical, a continuous transition from LH band to RH band without a bandgap can be achieved. In addition, because of the presence of SRRs, the resonant-type balanced CRLH CPW structure exhibits a very sharp cutoff in the lower edge of the transmission band.
