Antenna of window glass for automobile

Abstract

Abstract PURPOSE:To allow antenna elements to interact effetively as required, to improve the reception sensitivity and to make an insulator unnecessary to produce an antenna easily by arranging many antenna elements in spaces on both sides of a middle film of a joined glass. CONSTITUTION:Antenna elements 5 and 6 consisting of conductors are arranged in spaces A and B formed on both sides of a middle film 4 in a joined glass 1. Elements 5 and 6 form a crossing part 7 through the film 4, and its position is adjusted properly to eliminate the unnecessary interference of elements 5 and 6, and received radio waves of elements 5 and 6 are set to the same phase to improve the reception sensitivity of each antenna element. Since the film 4 is an insulator, elements 5 and 6 are separated from each other in DC though the crossing part 7 is formed, and a special insulator is not required.
