Estudio de los circuitos CRLH y sus aplicaciones en sistemas radiantes planares

Abstract

In this paper, an antenna patch based on the concept of composite right/left-handed (CRLH) materials is presented. This radiant system is capable of working in two bands. Varying the circuital components it is possible to control the frequency bands, this means these radiant structures show electronics control capabilities. Two different circuits have been developed under two points of view: One introduces a LHM (Left Handed Material) at the input port of the antenna affecting to the input matching and the other one controls the patch resonance. The equivalent circuits of these new structures have been obtained and proved with circuital and electromagnetics simulators. The experimental results and simulations show a good agreement.
