Patent ID: 7038631

Claim:
A wire-plate antenna comprising: a first electrically-conductive surface; a second electrically-conductive surface, forming a ground plane, parallel to the first surface; a first electrically-conductive feed wire or strip connecting a first terminal of a generator/receiver to the first surface; the second surface being connected to a second terminal of the generator/receiver; and at least one second electrically-conductive wire or strip connecting the two abovementioned surfaces, wherein the first surface includes a cutout-slot formed ofmutually extending sections, the cutout-slot stretching near and along an edge part of the first surface, the edge part being sufficiently extensive such that the cutout-slot defines an inner region of the first surface by forming most of the boundary of the inner region, thereby achieving a multi-frequency operation, wherein said at least one second electrically-conductive wire or strip connecting the first and second surfaces makes contact with the first surface inside the inner region.
