Abstract
The invention relates to an internal antenna element of the patch type for a portable device. The element comprises a body of dielectric material, a conductive plate covering the top face of the dielectric, and a conductive strip covering one of the side faces of the dielectric, the strip being electrically connected along its top edge to one of the edges of said plate and being provided with electrical connection means for connecting said conductive strip to a ground plane that is to be placed against the bottom face of the dielectric body, the other three side faces having no metallization, means passing through the dielectric body for electrically connecting the hot point of an antenna conductor to said plate, and capacitor-forming means for providing capacitance between the plate and the ground plane when the antenna element is mounted on the ground plane, and located close to the side face of the dielectric body that is remote from its side face covered by said conductive strip.
