Patent number: 8581792Abstract: A receiver apparatus includes: a main unit device; and a junction cable transmitting one or both of signal and electric power between the main unit device and an external device. The junction cable is a multicore coaxial cable having a plurality of core wire cables and a covered wire covering the plurality of core wire cables, and only the covered wire is cut locally so that the covered wire is divided into a main unit device-side covered wire and an external device-side covered wire. The main unit device transmits one or both of the signal and electric power by the core wire cable, and the main unit device-side covered wire or the core wire cable is connected to an antenna input port of a built-in tuner, and the main unit device receives a desired broadcast wave with the tuner using a high-frequency signal induced in the main unit device-side covered wire or the external device-side covered wire.Type: GrantFiled: August 27, 2009Date of Patent: November 12, 2013Assignee: Sony CorporationInventors: Kouichi Mukai, Yoshitaka Yoshino, Chisato Komori

Patent number: 8570838Abstract: An electronic timepiece with internal antenna maintains sufficiently high reception performance of circularly polarized waves even when having a metal external case. The timepiece has a cylindrical case; a crystal that covers the opening on the face side of the case; a drive mechanism that arranged inside the case; a metal antenna; and a dielectric. The antenna houses the drive mechanism and has a cylindrical side part, a bottom part that covers the opening on the back side of the side part, and an antenna electrode that contacts the inside of the side part. The back cover covers the back side of the case and is also the bottom part. The dielectric extends circumferentially to the side part, and contacts the antenna electrode in the face-back cover direction. A slot extending circumferentially is formed in the antenna electrode. Part or all of the slot is covered by the dielectric.Type: GrantFiled: November 10, 2011Date of Patent: October 29, 2013Assignee: Seiko Epson CorporationInventor: Teruhiko Fujisawa

Patent number: 8519906Abstract: The invention provides an antenna capable of performance similar to a Yagi-Uda antenna. However, unlike a conventional Yagi Uda antenna, the antenna of the invention is implementable on a substrate and thereby provides a directional antenna capable of disposition within a slender housing such as a cellular communications device. One embodiment of the invention provides an antenna comprising a substrate including a ground plane. The ground plane comprises a base portion and a spine portion extending from the base portion along a central axis of the substrate. A driven antenna element is disposed on a portion of the substrate and coupled to the spine portion to form a first antenna dipole. At least one antenna director element is disposed on a portion of the substrate and coupled to the spine portion to form a second antenna dipole. A reflector element comprises a portion of the ground plane.Type: GrantFiled: November 17, 2008Date of Patent: August 27, 2013Assignee: Loc8tor Ltd.Inventors: Anthony Richards, Andrew Ackland, Stephen Braithwaite
