1. An antenna array, comprising:
- a monolithic three dimensional grid of dielectric material having sidewalls defining a plurality of adjacent polygonal cells, said sidewalls having an upper and lower edge;
an antenna circuit formed on at least one of the sidewalls of a plurality of the cells, between the upper and lower edge thereof, to form a plurality of notch radiating elements having a horn shaped configuration, said radiating elements being positioned near the center of said sidewalls, andwherein each of said sidewalls is offset intermediate their ends so that approximately one-half of the sidewall is offset from another half, and the antenna circuitry comprises a notch formed by circuitry on opposite surfaces of the wall offset from one another;
a first sheet of dielectric material bonded to the upper edge of the grid serving as a structural outer skin and antenna radome; and
a second sheet bonded to the lower edge of each of the sidewalls serving as both a structural inner skin and as a member supporting interconnecting circuitry of the antenna.

Abstract
A tapered notch antenna structural panel array that can serve both as a structural member and an antenna is made from an injection molded monolithic three dimensional grid of thermoplastic material. The notch and feed line are in the form of microstrip or stripline circuitry formed to the sidewalls of adjacent cells. Dielectric sheets of material are bonded to the upper and lower edges of the grid. Interconnect circuitry on the antenna ground plane is supported by the sheet bonded to the lower edge and connected to the antenna circuitry of the sidewalls.
