Main Claim (1)
A wire-plate antenna of the type comprising: a first electrically-conductive surface (120); a
second electrically-conductive surface (140), forming a ground plane, parallel to the first
surface; a first electrically-conductive feed wire or strip (150) connecting a first terminal of
a generator/receiver to the first surface (120); the second surface (140) being connected
to a second terminal of the generator/receiver; and at least one second electricallyconductive wire or strip (160) connecting the two abovementioned surfaces (120, 140),
characterized in that the first surface (120) has a cutout-slot (122), or a series of cutoutslots (122), each cutout-slot being formed, possibly, of mutually extending sections, this
(or these) cutout-slot(s) (122) stretching to near and along an edge part of this first surface
(120), this edge part being sufficiently extensive in order that the cutout-slot(s) (122)
defines an inner region (126) of the first surface (120) by substantially forming most of the
periphery of this region (126), thereby achieving a multi-frequency operation.
