Abstract: A glass antenna device for an automobile including a rear window glass sheet; an electric heating type defogger formed on the glass sheet, which is provided with heater strips and positive and negative bus bars for feeding a current to the heater strips; and a noise filter including at least a coil, which is connected between the positive bus bar and a positive terminal of a d.c. power source for the defogger. The negative bus bar is grounded to the automobile body, and antenna conductors are provided in a region in the rear window glass sheet other than the region where the defogger is formed. An antenna conductor element of the antenna conductors extends substantially parallel to the heater strips of the defogger, is more than half in length than a width of the rear window glass sheet, and is located in the range of 15 mm-50 mm apart from an end heating strip of the heating strips of the defogger nearest to the antenna conductor element. The coil has an inductance value in the range of 0.5-10 .mu.H.

Abstract: An antenna attached to a window glass for transmitting and receiving ultrashort waves includes a primary antenna having a first feed point which is electrically connected therewith, a secondary antenna having a second feed point which is electrically connected therewith. A feeder is a coaxial cable having inner and outer conductors, an insulator disposed therebetween, and an outer cover covering the outer conductor. A first terminal which is electrically connected to the first feed point, a first holding portion for holding the inner conductor of the feeder so as to achieve an electrical connection between the first terminal and the inner conductor. A second terminal which is electrically connected to the second feed point has a second holding portion for holding the outer conductor of the feeder. The second holding portion has a through opening which is substantially rectangular or elliptical in shape for pouring thereinto a solder to achieve a soldering between the outer conductor and the holding portion.

Abstract: A second antenna is provided to a vehicle rear window glass in order to prevent a fall or dip of the gain of the antenna system in a particular direction or directions, thereby improving the directivity characteristic and increasing the gain. The second antenna consists of a feed point and a pair of first and second elements connected to the feed point. The first element has, in an area of the space above a first antenna or in a space defined between the upper and lower ends of a first antenna, at least one horizontal conductive strip. In one embodiment, in which the feed point is arranged in a marginal area of the space under the defogging heater element, the first element further has a vertical conductive strip arranged in an area of the space between the heater element and a lateral edge of the window glass.

Abstract: This invention provides a vehicle window glass antenna arranged in a space left below defogging heater strips for transmission and reception of ultrashort waves used for mobile phones and/or personal radios. The antenna section has a primary antenna which is a combination of a plurality of elongate elements connected to each other so as to form a closed plane figure having one to four vertexes each of which is acutely angled and pointed upward and becomes an upper end of the primary antenna. The plurality of elongate elements includes a single horizontally elongate element which becomes the bottom side of the plane figure. The antenna includes a secondary antenna section which is essentially a horizontally elongate element positioned below the primary antenna section. The antenna feeder is a coaxial cable, and the primary and secondary antenna sections are connected with the inner and outer conductors of the coaxial cable, respectively.

Abstract: The invention provides a vehicle window glass antenna for transmission and reception of ultrashort waves used for mobile phones and/or personal radios. The antenna has a primary antenna which is a combination of at least two vertical (in the sense of perpendicular to a horizontal line) elements and at least two horizontal elements each of which directly connects with at least one of the vertical elements and a secondary antenna which is essentially a horizontally elongate element located in a space between the primary antenna and the lower or upper edge of the window glass. The primary antenna is arranged within a rectangular area having a limited horizontal width and a limited length, and the horizontal element of the secondary antenna has a limited length. The antenna feeder is a coaxial cable, and the primary antenna and the secondary antenna are connected with the inner conductor and the outer conductor of the coaxial cable, respectively.

Abstract: The invention relates to an antenna on a vehicle rear window glass for the reception of FM radio broadcasting and TV broadcasting in both the VHF and UHF bands. The window glass is provided with defogging heater strips, and the antenna uses a space left above the heater strips. The antenna is essentially comprised of an L-shaped primary element with a vertical part on or close to the vertical center axis of the window glass and a horizontal part extending from the lower end of the vertical part, an impedance matching element located on one side of the vertical part of the primary element and an auxiliary element extending horizontally above the impedance matching element. The impedance matching element has two parallel horizontal parts, at least one vertical part connecting the two horizontal parts to each other and two extensions which extend vertically from the two horizontal parts, respectively, and bend to connect to the vertical part of the primary element.
