THROUGH-GLASS ANTENNA SYSTEM
First Claim
1. A through-glass antenna system, comprising:
- a patch antenna;
a three-dimensional conductive structure having a substantially planar surface serving as a ground plane for the patch antenna and further including bent and folded sides wherein one side includes a conductive surface that extends below the substantially planar surface and further bends at an approximate angle of a vehicle'"'"'s front or rear window;
a substantially planar external coupler having an inside portion and an edge portion, wherein the patch antenna is connected to the external coupler;
a substantially planar internal coupler having an inside portion and an edge portion, wherein the couplers are positioned opposite to each other; and
a low noise amplifier, wherein the low noise amplifier is connected to the internal coupler.

Abstract
A through-glass antenna system (10) includes a patch antenna (14) mounted on a horizontal flat surface (51) of a three-dimensional conductive structure (16). The structure can serve as a ground plane for the patch antenna and further include bent and folded sides (52, 54, and 56) where one side includes a conductive surface (52) that extends below the horizontal flat surface and if necessary further bends at an approximate angle of a vehicle'"'"'s front or rear window (30), a substantially planar external coupler (26) having an inside portion (63) and an edge portion (67) where the patch antenna is connected to the inside portion (63) of the external coupler, a substantially planar internal coupler (32) having an inside portion (7)3 and an edge portion (77), and a low noise amplifier (36) where the low noise amplifier is connected to the edge portion of the internal coupler.
