Abstract: The disclosure is directed to a vehicle window equipped with a radio antenna as well as a heating defroster. A laminated window glass is employed advantageously which comprises inner and outer plates of glass facing respectively the interior and exterior of the vehicle. The heating structure is mounted on a first surface of the laminated glass. At least part of the antenna elements is formed on a second surface which is different from the first surface supporting the heater elements. The antenna bearing surface and/or heater bearing surface may be any surface of the laminated glass; the outer surface of the outer glass plate should be excluded from the supporting surface, however, because such surface is exposed to the exterior of the vehicle. Therefore, a relatively large area is always available for the antenna structure irrespective of the size of the window. It becomes more flexible and easier to make the design of antenna having the desired characteristics.

Abstract: An antenna element conductor is formed on a transparent insulating film. An adhesive is applied to the rear surface of the film. A connector is provided to a feeder terminal. A print antenna comprising the film and the antenna conductor can be attached to a glass surface, and a position of the antenna on the window glass can be desirably selected so as to obtain good antenna characteristics.

Abstract: An antenna element is mounted on a glass of a rear quarter window of a vehicle along the edge thereof. A coupling element is provided midway along said antenna element for coupling between two segmented elements with phase adjustment between reception signals thereof in a specific frequency range. The coupling element connects the two segmented elements in lower frequency range, and disconnects the two elements in higher frequency range. The length of the antenna element is automatically corrected in respective low and high frequency ranges so as to cover a wide range.

Abstract: Windshield glass for a vehicle is disclosed including heating conductive wires for defogging and antenna wires for receiving a radio wave. The reception signal of the antenna is derived from an output at the center of the windshield glass and is led out through a lead wire to a feeding point positioned at a side portion of the windshield glass. A pair of auxiliary elements extends over a whole length of upper and lower sides of the lead wire. The auxiliary elements are connected to one of a pair of power supply buses of the heating conductive wires for removing influence of the lead wire on reception characteristics of the antenna.

Abstract: A pair of antenna elements are mounted on a glass of a rear quarter window of a vehicle. Feed points of these elements are provided at a corner portion of the window. One antenna element extends clockwise about the center of the window glass and the other antenna element extends counterclockwise thereabout from their corresponding feed points. The characteristics of both antenna elements significantly differ and complement each other. It is convenient for a diversity reception system. An auxiliary element branches from one antenna element to extend along the other antenna element. The auxiliary element compensates for impedance characteristics of the antenna elements to tune up reception characteristics thereof.

Abstract: A glass sheet with broad band receiver antennae and an area to be heated, comprising a glass sheet, a first means provided in the heating area of the glass sheet and capable of functioning both as a heating conductor wire and as a first receiver antennae for receiving waves in predetermined frequency band, an electric source connected to the first means for supplying a heating current to the first means, and a second means provided in an area of the glass sheet other than the heating area and capable of functioning as second receiver antennae for receiving waves in a frequency band different from the frequency band for the first receiver antennae. This glass sheet further includes a stub one end of which is connected to the first means and the other of which to the second means, and a feeder connected to the second means.
