CA 2331367

A patch antenna (10) having enhanced frequency response has a generally planar element formed of a substantially conductive material, and antenna feed conductor (14) electrically connected to the antenna element, and a generally planar parasitic element (20) formed of a substantially conductive material positioned substantially coaxially with respect to the antenna element and spaced apart therefrom. The distance by which the parasitic element is spaced apart from the antenna element in order to provide such enhanced frequency response of the patch antenna is determined empirically. An optimally configured array of such patch antennas is also disclosed.

L'invention concerne une antenne à plaque (10) à réponse de fréquence améliorée. Cette antenne possède généralement un élément planaire constitué d'une matière sensiblement conductrice, un conducteur (14) d'alimentation d'antenne connecté électriquement à l'élément de l'antenne et un élément non alimenté (20) généralement planaire constitué d'une matière sensiblement conductrice disposée de façon sensiblement coaxiale par rapport à l'élément d'antenne et espacée par rapport à celui-ci. La distance à laquelle l'élément non alimenté est espacé par rapport à l'antenne afin de produire la réponse de fréquence améliorée de l'antenne à plaque est déterminée empiriquement. L'invention concerne également un réseau d'antennes à plaques selon l'invention configuré de façon optimale.
