Patent ID: 7064722

Claim:
A dual polarized broadband tapered slot antenna comprising: (i) a support structure having first, second, third and fourth dielectric side walls, each of the side walls of said support structure having a trapezoidal shape, the first, second, third and fourth side walls of said support structure being configured to have a rectangular shaped base, and a rectangular shaped upper end; and (ii) a pair of antenna boards co-located within said support structure and affixed to said support structure, said first and second antenna boards being positioned perpendicular to one another, each of said first and second antenna boards including: (a) a dielectric substrate; (b) a tapered slot antenna mounted on an upper surface of the dielectric substrate for said first and second antenna boards, said tapered slot antenna for said first and second antenna boards having a radiating metallic antenna element mounted on the upper surface of the dielectric substrate for said first and second antenna boards and a centrally located tapered slot which consists of a portion of said radiating metallic antenna element etched away to expose said dielectric substrate; and (c) a microstrip feed line mounted on a lower surface of the dielectric substrate for said first and second antenna boards, said microstrip feed line for said first and second antenna boards being connected to said radiating metallic antenna element for said first and second antenna boards by a copper plated through hole which passes through the dielectric substrate for said first and second antenna boards.
