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: An antenna is attached to a rear window glass of an automobile and arranged in a space between a defogging heater element and a lower edge of the window glass. According to an aspect of the present invention, the antenna comprises a plurality of horizontal conductive strips having the length of 0.02.lambda..multidot.f.sup.1/2 (1.+-.0.2), adjacent two of which are connected at opposite ends so as to constitute a rectangular loop. The number of the horizontal conductive strips is in the range of 2 to 4.

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 a combination of a main antenna and a secondary antenna, and every element of the antenna is a conductive strip. The main antenna has at least two horizontally extending primary elements which are parallel to and at a relatively short distance from each other. Each of the primary elements has a length of 300-550 mm and is connected at its one end to the other(s) by a subsidiary element arranged perpendicular to the primary elements. The secondary antenna has a middle part, which is relatively long and extends horizontally, and two extension parts which extend from the two opposite ends of the middle part parallel and close to the two opposite side edges of the window glass, respectively.

Abstract: The invention relates to an antenna attached to a vehicle roof glass, i.e. a glass plate fitted in an opening of the roof of a vehicle body, for receiving FM radio and TV broadcast waves in both the VHF band and the UHF band. Essentially the antenna is comprised of a main element which is combination of two linear segments each of which is a conductive strip attached to the roof glass, a feed point attached to the roof glass and a connection line which connects the main element to the feed point and extends parallel or nearly parallel to the longitudinal center axis of the vehicle body. The two linear segments of the main element extend respectively obliquely with respect to the aforementioned center axis and intersect each other. It is suitable that the two linear segments have the same length and bisect each other. Optionally the antenna may include an auxiliary element attached to the roof glass and connected to the feed point.

Abstract: The invention relates to a wide-band antenna attached to a vehicle window glass such as an automobile windshield for receiving FM radio and TV broadcast waves. Each element of the antenna is a conductive strip. The antenna is comprised of a main element and an impedance matching element to make a resistance component of the impedance of the antenna equal to or greater than that of coaxial cable used as the feeder for the antenna. The main element has a vertical part in a widthwise central region of the window glass with its one end at a short distance from either the lower edge or the upper edge of the glass and a horizontal part which extends from that end of the vertical part to a side marginal region of the glass. A feed point of the antenna is in a lower end portion of the side marginal region of the glass. When the horizontal part is close to the lower edge it terminates at the feed point, and the impedance matching element is connected to the horizontal part.

Abstract: On a vehicle window glass provided with defogging heater strips, such as automobile rear window glass, the invention provides an antenna of improved efficiency for receiving FM and AM radio broadcast waves. In an area left above the heater strips the antenna is constructed of at least three elements each of which is a conductive strip. The first and main element is a T-shaped element with its horizontal part at a short distance from the upper edge of the window glass. On one side of the vertical part of the T-shaped element, the second element extends horizontally from a point on that vertical part. The third element, which is located on the other side of that vertical part, has a primary part which constitutes at least three sides of a horizontally elongate rectangle and a secondary part which extends horizontally from a point on the vertical part of the T-shaped element and connects with the primary part. A lead extends from a side of the rectangle to a feed point.
