CA 2507520

A multiple-band antenna having first and second operating frequency bands is provided. The antenna includes a first patch structure associated primarily with the first operating frequency band, a second patch structure electrically coupled to the first patch structure and associated primarily with the second operating frequency band, a first slot structure disposed between a first portion of the first patch structure and the second patch structure and associated primarily with the first operating frequency band, and a second slot structure disposed between a second portion of the first patch structure and the second patch structure and associated primarily with the second operating frequency band. A mounting structure for the multiple-band antenna is also provided. The mounting structure includes a first surface and a second surface opposite to and overlapping the first surface. The first and second patch structures are mounted to the first surface, and a feeding point and ground point, respectively connected to the first and second patch structures, are mounted to the second surface.

L'invention porte sur une antenne à bandes multiples possédant des première et seconde bandes de fréquence de fonctionnement. L'antenne comprend une première structure de connexion associée à la base à la première bande de fréquence de fonctionnement, une seconde structure de connexion couplée électriquement à la première et associée à la base à la seconde bande de fréquence de fonctionnement, une première structure à fentes rayonnantes disposée entre une première partie de la première structure de connexion et de la seconde structure de connexion et associée à la base à la seconde bande de fréquence de fonctionnement. L'invention porte également sur une structure de montage de l'antenne à bandes multiples. La structure de montage comprend une première surface et une seconde surface opposée à la première et la chevauchant. Les première et seconde structures de connexion sont montées sur la première surface, et un point d'alimentation et un point de masse, connectés respectivement aux première et seconde structures de connexion, sont montés sur la seconde surface.
