An antenna assembly is formed on a rectangular polyhedron support that has two sections projecting away from opposite sides of an electrically non-conductive substrate. An electrically conductive stripe wraps around the support and comprises a plurality of segments on different surfaces of the support. A conductive patch is located on two surfaces of the support to provide impedance matching between the antenna and a radio frequency circuit. By placing sections of the antenna assembly on both sides of the substrate and wrapping the conductive stripe around those sections, the space required to accommodate the antenna assembly within a housing of a communication device is reduced, as compared to some prior antenna designs.
L'invention porte sur un ensemble antenne qui est formé sur un support en forme de polyèdre rectangle qui comprend deux sections faisant saillie de côtés opposés d'un substrat électriquement non conducteur. Une bande électriquement conductrice est enroulée autour du support et comprend une pluralité de segments sur différentes surfaces du support. Une plaque conductrice est placée sur deux surfaces du support pour assurer une adaptation d'impédance entre l'antenne et un circuit radiofréquence. En plaçant des sections de l'ensemble antenne sur les deux côtés du substrat et enroulement de la bande conductrice autour de ces sections, l'espace requis pour loger l'ensemble antenne à l'intérieur d'un boîtier d'un dispositif de communication est réduit, par comparaison avec certains modèles d'antenne antérieurs.
