Plate antenna
First Claim
1. A patch type antenna system comprising:
- groundplane-forming means; and
a radiating element disposed facing the groundplane-forming means and disposed at a predetermined distance from the plane;
the system being characterized in that it further comprises;
a passive component (16) entirely disposed facing said radiating element (12) without direct electrical contact therewith so as to provide electromagnetic coupling between said passive component and said radiating element, said passive component having no mechanical connection between itself and the radiating element so as to leave an empty gap between itself and the radiating element, said passive component being isolated from the groundplane-forming means and being electrically connectable to the antenna feed point, and in that said antenna system has no means forming a short circuit between said radiating element and said groundplane-forming means.

Abstract
The invention relates to a patch type antenna comprising:
a ground plane (10); and
a radiating element disposed facing the groundplane-forming means.
The antenna further comprises:
a passive component (16) disposed entirely facing said radiating element (12) without direct electrical contact therewith in order to provide electromagnetic coupling between said passive component and said radiating element, said passive component having no mechanical connection between itself and the radiating element so that an empty space exists between itself and the radiating element, said passive component being isolated from the ground plane and being electrically connectable to the antenna feed point. In addition, said antenna system does not have a short-circuit between said radiating element and the ground plane.
