In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

Coupling phenomena between artificial left-handed ~LH! transmission lines are explored on the basis of a transmission line approach of LH materials. A LH forward coupler in the form of an ideal lumped-element ladder network is presented and is shown to exhibit strong forward coupling that increases with decreasing of frequency. A quasi-lumped element microstrip implementation of a LH coupler is...

A left-handed transmission line with regularly spaced Schottky varactors is experimentally characterized. Due to dispersion, an envelop pulse on the line experiences a great distortion. By measuring the test line, we successfully observed that this distortion is compensated for by the nonlinear effects of Schottky varactors. This article describes the experimental observations, together with fu...

This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are s...

This paper presents a realization of composite right/left handed transmission lines using coupled microstrip lines. This structure exploits the advantages of the microstrip lines, while increases the coupling by a floating conductor at the ground plane. The performance of this composite right/left-handed line is demonstrated by both simulated and measured results, and they show good agreement. ...
