Patent number: 5079560Abstract: A vehicle window glass is provided with an antenna to be fit in a window frame of a vehicle such as an automobile. The antenna comprises a plurality of antenna elements which are disposed on a portion of the glass extending generally alongside the window frame. Thus, the antenna elements are spaced from the window frame at a reference or ground potential and preferably close to the sides of the frame. The antenna elements are each designed to have a different length from one another so that they can receive radio waves covering a relatively broad frequency band with a relatively high sensitivity.Type: GrantFiled: August 30, 1990Date of Patent: January 7, 1992Assignee: Nippon Sheet Glas Co., Ltd.Inventors: Kaoru Sakurai, Harunori Murakami, Hiroshi Iijima, Hajime Murakami

Patent number: 5017933Abstract: 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.Type: GrantFiled: March 22, 1989Date of Patent: May 21, 1991Assignee: Nippon Sheet Glass Co., Ltd.Inventors: Kaoru Sakurai, Masaru Maeda, Harunori Murakami, Hiroshi Iijima
