DOI: 10.1080/09205071.2018.1552538
Abstract: ABSTRACT This paper presents a simplified composite right/left-handed trans-mission-line (SCRLH-TL) unit-cell, which is primarily consisted of a rectangular ring with two grounded vias. Superposing this unit-cell onto a high–low–high step-impedance resonator (SIR) leads to a… read more here.
