Abstract
An antenna assembly comprises a dome-like substrate with a ground plane layer on the interior surface of the substrate and a radiative patch on the outer surface of the substrate. The cavity defined by the substrate is closed off by a base having a conductive layer that is connected to the ground plane layer, thereby to isolate the cavity and circuit elements that may be disposed therein. Preferably the substrate has a polyhedral form and the radiative patch is a polygon having apex portions that extend down over the side surface of the substrate to enhance the sensitivity of the antenna at low elevations.
