Análisis y Diseño de Monopolos Acoplados para Dispositivos Móviles Multibanda
(XXIII Simposium Nacional de la Unión Científica Internacional de Radio, Madrid, del 22-24 septiembre 2008, 2008-09)
A novel low profile planar antenna is proposed. The
antenna presented is a coupled monopole antenna, comprising
at least a driven element coupled with one or more parasitic
elements. The design proposed ...
Analisi de l'avaluació incremental i de l'aplicació eficient de l'Algorisme Genètic en un Sistema Classificador
