Patent

CA 2670535

A multiple-antenna device is provided, comprising: a printed circuit board having a ground plane configured to provide electromagnetic isolation between a first side of the printed circuit board and a second side of the printed circuit board; a first non-conductive support member formed over the first side of the printed circuit board; a second non-conductive support member formed over the second side of the printed circuit board; a first antenna formed over the first non-conductive support member; and a second antenna formed over the second non-conductive support member, wherein the first antenna is electrically connected to a first feed point on a first portion of the printed circuit board that is not connected to the ground plane, and wherein the second antenna is electrically connected to a second feed point on a second portion of the printed circuit board that is not connected to the ground plane.

L'invention concerne un dispositif à antennes multiples comprenant : une carte de circuits imprimés présentant un plan de sol conçu pour fournir une isolation électromagnétique entre un premier et un second côté de la carte de circuits imprimés; un premier élément de support non conducteur situé sur le premier côté de la carte de circuits imprimés; un second élément de support non conducteur situé sur le second côté de la carte de circuits imprimés; une première antenne placée sur le premier élément de support non conducteur; et une seconde antenne placée sur le second élément de support non conducteur, la première antenne étant connectée électriquement à un premier point d'alimentation sur une première partie de la carte de circuits imprimés qui n'est pas connecté au plan de sol et la seconde antenne étant connectée électriquement à un second point d'alimentation sur une seconde partie de la carte de circuits imprimés qui n'est pas connecté au plan de sol.
