Publication number: 20130249747Abstract: The present invention is directed to achieving a favorable grounding state in a vehicle-mounted antenna. One end of a bent antenna element 22 is connected to an inner conductor of a coaxial cable 14 via a wiring conductor pattern of a substrate 12. An outer conductor of the coaxial cable 14 is connected to a front grounding conductor pattern of the substrate 12. In the substrate 12, a plate capacitor is formed by the front grounding conductor pattern, a rear grounding conductor pattern, and a dielectric plate sandwiched between these grounding conductor patterns. The outer conductor 52 of the coaxial cable 14 is electrically connected to one end of a grounding bracket 20 via the plate capacitor. A tip portion 24 of the grounding bracket 20 is secured to a vehicle body by means of a bolt 26 and is electrically connected to the vehicle body.Type: ApplicationFiled: February 4, 2013Publication date: September 26, 2013Applicant: Kojima Press Industry Co., Ltd.Inventor: Kei HIJIRIKAWA

Patent number: 8502742Abstract: 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: September 5, 2012Date of Patent: August 6, 2013Assignee: Harada Industry Co., Ltd.Inventors: Masashi Wakui, Akio Kamiya, Nobuo Arayama
