1. An antenna assembly comprising:
- A. a dome-like substrate having a surface with a top portion and side portions extending from said top portion, said side surface portions defining an opening opposite said top surface portion;
B. a ground plane layer on the interior surface of said substrate;
C. a radiative layer on the exterior surface of said substrate, said radiative layer having a central portion on said top surface portion and apex portions extending from said top surface portion and down over the side surface portions; and
D. a base contacting said substrate and closing said opening, said base having a first surface facing the interior of said substrate and a second surface opposite said first surface.

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.
