Publication number: 20130057443Abstract: A radiators has looped radiation conductors, an inductor, a capacitor, a feed point on the radiation conductor. The capacitor is formed by a capacitance between the radiation conductors, and the capacitance varies depending on positions on the radiation conductors within a portion where the radiation conductors are close to each other. The radiators is configured to: resonate along a portion of the radiator at a low-band resonance frequency, the portion including the inductor and the capacitor and being along the loop of the radiation conductor, and resonate along a portion of the radiator at a high-band resonance frequency, the portion including a section along the loop of the radiation conductor, the section including at least one of the at least one capacitor, not including the inductor, and extending between the feed point and the inductor.Type: ApplicationFiled: January 31, 2012Publication date: March 7, 2013Inventors: Kenichi Asanuma, Atsushi Yamamoto, Tsutomu Sakata, Kenichi Kozaki

Publication number: 20110102270Abstract: An antenna comprises the followings: a base substance provide on a substrate 8; a conductive film made on the base substance; and a gap 5 that electrically divides the conductive film into a first conductive film 6 and a second conductive film 7. The first conductive film 6 is connected to a power supply section provided on the substrate 8, and the second conductive film 7 is connected to a ground section 9 by way of a conductor. The power supply section, the first conductive film 6, the gap 5, the second conductive film 7, a conductor 11, and the ground section 9 are serially connected in this sequence.Type: ApplicationFiled: October 29, 2010Publication date: May 5, 2011Applicant: PANASONIC CORPORATIONInventors: Yasuki NAGATOMO, Kenichi KOZAKI, Kazuhide GOTOU

Patent number: 7170453Abstract: An antenna apparatus includes a plurality of antennas having different resonance frequencies and a feeding section for supplying common power to feeding terminals of the plurality of antennas. Open terminals of the plurality of antennas are separate. As at least one of the plurality of antennas is implemented as a helical antenna having a helical conductor section trimmed, the transmission-reception band can be put into a wide band. Further, an antenna apparatus includes a plurality of antennas, a connection conductor provided between the antennas for connecting the antennas in series, a feeding section provided in one of terminal sections to which the connection conductor is not connected in the plurality of antennas connected in series, and an additional conductor provided in the other terminal section to which the connection conductor is not connected, wherein the additional conductor is an open end part.Type: GrantFiled: August 30, 2004Date of Patent: January 30, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshiharu Noguchi, Munenori Fujimura, Hiromi Tokunaga, Kenichi Kozaki, Shigefumi Akagi, Shuichiro Yamaguchi, Keisuke Maruyama

Patent number: 7042418Abstract: A chip antenna includes a substrate, a plurality of helical conductors provided on the substrate, and a pair of terminals provided on the substrate. One of the plurality of helical conductors is connected electrically to one of the terminals, and another one of the helical conductors is connected electrically to the other terminal. Thus, the antenna is of a small size, yet is a single unit which alone is capable of transmitting and receiving electromagnetic waves of a plurality of frequencies.Type: GrantFiled: November 19, 2003Date of Patent: May 9, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Munenori Fujimura, Hiromi Tokunaga, Shuichiro Yamaguchi, Toshiharu Noguchi, Kazuhiro Eguchi, Kenichi Kozaki, Shigefumi Akagi

Patent number: 6765805Abstract: A circuit component comprising a circuit board and a terminal for mounting the circuit board on a second circuit board. A length of the circuit board is 10 mm-80 mm, a difference in a coefficient of thermal expansion between the circuit board and the second circuit board is 0.2×10−5/° C. or greater. The terminal is made of an elastic material, and comprised of a first connection section, a second connection section and an elastic section disposed between the first and second connection sections, and the terminal separates the circuit board from the second circuit board by 0.3 mm-5 mm. In the circuit components of the present invention, deterioration in the conduction between the circuit board and the second circuit board due to heat cycles can be prevented. Thus, a circuit component having stable operating characteristics for a long period of time is obtained.Type: GrantFiled: October 3, 2001Date of Patent: July 20, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takumi Naruse, Kenichi Kozaki, Kazuhiro Eguchi, Katsumi Sasaki
