I n this paper, two novel ultra wideband (UWB) minimized antennas based on the composite right/left-handed transmission line (CRLH-TL) structures are designed.

In this study, we propose a composite right/left-handed (CRLH) cuboid antenna operating in the very-high-frequency band. The proposed uses CRLH transmission-line structure for miniaturization, and left-handed component is implemented using interdigital capacitors meander lines. A three-dimensional was designed to increase parallel inductance by applying line side of structure. operates at 252.5...

This paper presents a closed-form analysis of composite right/left handed transmission lines. The ladder network structure of the transmission line allows to obtain a rational form of any twoport network representation. As a consequence of the rational form of the transfer functions, poles and residues are easily computed and the dominant ones selected leading to an efficient time-domain macrom...

Decades ago, Veselago [1] predicted that a material with simultaneously-negative electric and magnetic polarization responses would yield a "left-handed" (LH) medium in which light propagates with opposite phase and energy velocities a condition described by a negative refractive index. He proposed that a flat slab of LH material possessing an isotropic refractive index n = -1 could act like an...

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...
