PURPOSE:To bring a directional characteristic to non-directivity without reducing the average gain, by bending the end part of the ultrashort wave receiving antenna to the opposite side against the heating conductive wire and also bending it so that it can be parallel, in case of an antenna mounted to the rear window glass of a car. CONSTITUTION:The heating conductive wire group 10 is provided so that several lines of the heating conductive wire 11 can be connected to the bus bars 12, 13 on the surface of the rear window glass 1 of a car. And in its upper side, an ultrashort wave antenna 14 which is extended in parallel with the heating conductive wire 11 and is bent at its end is mounted to the rear window glass 1. Furthermore, a stub 18 and an auxiliary line 19 which connect a feeder line extending upward vertically from the start point of the antenna 14 and extending along the upper edge of the glass 1, and a lead wire 17 connected to the heating conductive wire 11 are provided in the window glass 1. |
