Patent number: 8842052Abstract: An antenna apparatus that can suppress sensitivity degradation as much as possible to receive AM broadcasts and FM broadcasts even if an antenna height is decreased to 70 mm or less. An antenna board is vertically mounted on a planar antenna base, and a top portion is disposed to stride over the antenna board. An antenna element includes the top portion and an antenna pattern formed on the antenna board. A distance between the antenna base and a lower edge of the top portion is not less than 10 mm, and the lower edge of the top portion is bent downward. The top portion is configured such that an antenna capacitance of the antenna element becomes about 3 pF or more. A received signal from the antenna element is guided to an amplifier board through a connecting wire and amplified. An antenna case is fitted in the antenna base.Type: GrantFiled: February 22, 2013Date of Patent: September 23, 2014Assignee: Harada Industry Co., Ltd.Inventors: Masashi Wakui, Akio Kamiya, Nobuo Arayama

Patent number: 8421693Abstract: Good electric characteristics are obtained even after an antenna being further incorporated into an antenna apparatus including an antenna case having a limited space. An antenna device 31 is formed on an antenna substrate 30 installed upright in an antenna base 20. A flat antenna unit 35 is fastened to the antenna base 20 so that the flat antenna unit 35 is immediately below the antenna device 31. If the wavelength of a center frequency in an operating frequency band of the flat antenna unit 35 is ?, an interval between an upper surface of the flat antenna unit 35 and a lower end of the antenna device 31 is set to about 0.25 ? or more. Accordingly, it becomes possible to make directional characteristics of radiation in a horizontal plane of the flat antenna unit 35 non-directive without being affected by the antenna device 31 and also to achieve good gain characteristics.Type: GrantFiled: August 22, 2008Date of Patent: April 16, 2013Assignee: Harada Industry Co., Ltd.Inventors: Motoki Ohshima, Jinichi Inoue, Masashi Wakui, Nobuo Arayama
