Abstract
A method of integrating a thin antenna module into a vehicle is disclosed. The thin antenna module comprises a high impedance surface with at least one antenna element disposed thereon. The method includes the steps of inserting the thin antenna module between a conductive layer and a dielectric layer located above a passenger compartment of said vehicle, and connecting at least one antenna element disposed on the high impedance surface to a receiver in said vehicle.

A method of integrating a thin antenna module into a vehicle, the thin antenna module comprising a high impedance surface with at least one antenna element disposed thereon, the method comprising the steps of:
- inserting the thin antenna module between a conductive layer and a dielectric layer located adjacent a compartment of said vehicle, and
- connecting at least one antenna element disposed on the high impedance surface to a receiver in said vehicle.
A antenna mounted on a vehicle, said antenna comprising:
- (a) a ground plane formed by a structural portion of said vehicle;
- (b) a high impedance surface mounted on said ground plane formed by a structural portion of said vehicle, said high impedance surface comprising:
- (1) at least one layer of a dielectric material;
- (2) a plurality of conductive elements arranged in an array and disposed adjacent one surface of said at least one layer of a dielectric material;
- and
- (3) a ground plane layer disposed adjacent another surface of said at least one layer of a dielectric material;
- and
- (c) at least one antenna element disposed on said high impedance surface adjacent said plurality of conductive elements arranged in an array, said antenna element having at least one major axis which is parallel to said array when said at least one antenna element is disposed on said high impedance surface adjacent said plurality of conductive elements.
An antenna mounted on a vehicle, said antenna comprising:
- (a) a sheet of dielectric material forming a portion of said vehicle;
- (b) a ground plane sheet disposed adjacent a headliner in said vehicle, said headliner being disposed in said vehicle in a confronting relationship with the sheet of dielectric material;
- (c) a high impedance surface comprising:
- (1) at least one layer of a dielectric material;
- (2) a plurality of conductive elements arranged in an array and disposed adjacent one surface of said at least one layer of dielectric material;
- and
