Claim 4

Assembly according to claim 2, wherein said FM band segment is arranged generally along said center line portion, and said signal pickup point is arranged at said center line portion and generally adjacent to one of said horizontal edge portions.

Claim 5

Assembly according to claim 2, wherein said FM band segment and signal pickup point are arranged generally adjacent to but at a selective distance from one of said side edge portions, and said signal pickup point is arranged generally adjacent to one of said horizontal edge portions.

Claim 6

Assembly according to claim 1, wherein the window has generally horizontal top and bottom edge portions, generally vertical opposed side edge portions, and a generally vertical center line portion, and said segments include substantially vertical segments and substantially horizontal segments for reception in the AM short, medium and long wave band which are correspondingly perimetrically arranged closely adjacent to at least a part of at least some of said edge portions and said AM band segments terminate at said single free end of the wire.

Claim 7

Assembly according to claim 5, wherein said free end of the wire terminates generally adjacent to one of said side edge portions.

Claim 8

Assembly according to claim 6, wherein the inductor is arranged generally adjacent to one of said side edge portions and the free end of the wire terminates closely adjacent to the inductor.

Claim 9

Assembly according to claim 5, wherein said free end of the wire terminates at said center line portion.

Claim 10

Assembly according to claim 8, wherein the inductor is arranged at said center line portion and the free end of the wire terminates closely adjacent to the inductor.

Claim 11

Assembly according to claim 5, wherein said AM band segments are correspondingly arranged closely adjacent to at least three of said edge portions.

Claim 12

Assembly according to claim 5, wherein said AM band segments are correspondingly arranged closely adjacent to at least one of said edge portions and to only part of at least another of said edge portions adjacent to said at least one edge portion.

Claim 13

Assembly according to claim 5, wherein said AM band segments are correspondingly arranged closely adjacent to only one of said horizontal edge portions and to the corresponding partial portions of said side edge portions which are adjacent to said only one horizontal edge portion and remote from the other said horizontal edge portion.

Claim 14

Assembly according to claim 1, wherein the inductor is provided with a box rib pattern of selectively calculated dimensions for optimizing the total length of the single conductor wire.

Claim 15

Assembly according to claim 1, wherein said assembly is operatively mounted in a motor vehicle window opening.

Claim 16

Multiband aerial window pane assembly, such as for a motor vehicle, which comprises an aerial window having an aerial circuit formed of a single continuous conductor wire, commencing from a signal pickup point and terminating in a single free end, said window having generally horizontal top and bottom edge portions, generally vertical opposed side edge portions, and a generally vertical center line portion, said wire including an aerial section for FM and an aerial section for AM connected in series so as not to require phasing and being electrically isolated from each other by an inductor which is arranged to function in open circuit for the FM band and in short circuit for the AM band, said aerial sections including a series of corresponding generally vertical segments and generally horizontal segments which are arranged in a selective geometrically asymmetrical configuration for forming the aerial, and said segments including a corresponding vertical segment for reception in the FM ultra short wave band commencing from said signal pickup point and terminating at said inductor, and further including corresponding vertical and horizontal segments for reception in the AM short, medium and long wave band which are correspondingly perimetrically arranged closely adjacent to at least a part of at least some of said edge portions and which commence from said signal pickup point and terminate at said single free end of the wire and which operate when said inductor functions in short circuit.

Claim 17

Multiband aerial window pane assembly, such as for a motor vehicle, which comprises an aerial window having an aerial circuit formed of a single continuous conductor wire, commencing from a signal pickup point and terminating in a single free end, said window having generally horizontal top and bottom edge portions, generally vertical opposed side edge portions, and a generally vertical center line portion, said wire including an aerial section for FM and an aerial section for AM connected in series so as not to require phasing and being electrically isolated from each other by an inductor which is arranged to function in open circuit for the FM band and in short circuit for the AM band, said aerial sections including a series of corresponding generally vertical segments and generally horizontal segments which are arranged in a selective geometrically asymmetrical configuration for forming the aerial, and said segments including a corresponding vertical segment for reception in the FM ultra short wave band commencing from said signal pickup point and terminating at said inductor, and further including corresponding vertical and horizontal segments for reception in the AM short, medium and long wave band which are correspondingly perimetrically arranged closely adjacent to at least a part of at least some of said edge portions and which commence from said signal pickup point and terminate at said single free end of the wire and which operate when said inductor functions in short circuit.
