Abstract
An antenna having a plurality of conductive layers formed on a dielectric substrate. A ground plate and a feed plate are oriented in substantially parallel relation on two opposing sides of the dielectric substrate. A top plate, which is electrically connected to the ground plate and electrically insulated from the feed plate, is disposed on a third surface of the dielectric substrate perpendicular to the first and the second surfaces. One or more conductive layers are also disposed within the interior of the dielectric substrate parallel to the first and the second surfaces. One or more conductive vias extend between the feed plate and the ground plate through the interior of the dielectric substrate. In various embodiments these conductive vias are connected to one or more of the feed plate, the ground plate, and the interior conductive surfaces.
