SLOT ANTENNA IN A SOLAR-REFLECTIVE GLAZING
First Claim
1. A system for providing an antenna feed to a slot antenna, the system comprising:
- a layer of conductive solar-reflective material, formed with a slot such that the layer of conductive solar-reflective material is adapted to operate as a slot antenna;
a first dielectric layer attached to the layer of conductive solar-reflective material; and
an antenna feed attached to the first dielectric layer on the opposite side from the layer of conductive solar-reflective material, adapted to provide a driving frequency to the layer of solar-reflective material.

Abstract
The described method and system provide an antenna feed for a slot antenna that may be patterned into a solar-reflective glazing layer with a virtual ground that is a short electrical distance from the antenna. One implementation of the present invention provides an antenna feed for a slot antenna patterned into the solar-reflective glazing used in a vehicle windshield. Because the antenna feed may incorporate a virtual ground that is a short electrical distance from the slot antenna, antenna performance may be improved over conventional on-glass vehicle antenna systems which use the vehicle chassis as a ground. Furthermore, patterning the slot antenna into the solar-reflective glazing layer and using a virtual ground in the antenna feed provides flexibility in antenna placement.
