An RF antenna system is disclosed having at least one meandering antenna line with an aggregate structure formed to substantially extend in two dimensions, to effectively form a dipole antenna. The meandering antenna line includes at least one localized bend for providing a compressed effective antenna length in a compact package. The present antenna can be made as an antenna system having discrete transmit and receive antenna lines, so as to form a dual antenna system. The localized bends on each line electromagnetically couple with the respective bends on the other line, thus increasing electromagnetic coupling efficiency, thereby increasing antenna bandwidth and gain.

Cette invention concerne un système d'antenne radiofréquence qui comprend au moins une ligne d'antenne sinueuse et une structure agrégative s'étendant dans deux dimensions, ceci de manière à former efficacement une antenne dipôle. La ligne d'antenne sinueuse comprend au moins une courbure localisée de manière à obtenir une longueur d'antenne efficace et comprimée dans un emballage compact. Cette antenne peut consister en un système d'antenne qui comprend des lignes d'antenne d'émission et de réception discrètes, ceci de manière à former un système d'antenne double. Les courbures localisées sur chaque ligne sont couplées par voie électromagnétique aux courbures respectives de l'autre ligne, ce qui permet d'augmenter l'efficacité de couplage électromagnétique et d'accroître ainsi la largeur de bande ainsi que le gain de l'antenne.
