Transparent window antenna.

摘要

A slot antenna formed in combination with a vehicle window. An electrically conducting, optically transparent film panel (16) is bonded to the window (12) and terminates so that its outer peripheral edge (22) is spaced from the innermost edge (20) of the metal framing the window to define a polygonal antenna slot (24) between the edges (20,22). An unbalanced transmission line is connected to the antenna by connecting the grounded conductor (26) to the framing metal near the metal (28) edge and coupling the ungrounded conductor (30) to the conductive panel (16) near the juxtaposed, interfacing edge of the conductive panel. <IMAGE>
