Patent number: 8948707Abstract: A transceiver module and duplexer within a communication device supports a minimized antenna volume and enhances a transfer gain for transmit and receive channels. The duplexer is communicatively coupled to one of multiple antenna and filter matching configurations which include a first configuration that couples receive and transmit filter matching circuits to a single antenna matching circuit. When the duplexer is coupled to the first configuration, receive and transmit filters of the duplexer are respectively coupled to the receive filter matching circuit and the transmit filter matching circuit. As a result, the antenna matching circuit and the filter matching circuits collectively provide the enhanced transfer gain.Type: GrantFiled: January 7, 2013Date of Patent: February 3, 2015Assignee: Google Technology Holdings LLCInventors: Richard E. Mach, Gregory R. Black

Publication number: 20140340273Abstract: There is provided an antenna apparatus capable of stably communicating with a communication partner and increasing the maximum possible communication range even when the antenna apparatus is relatively smaller than an antenna in the communication partner and the two antennas are disposed in close proximity on the same axis. A magnetic flux passing through a coil aperture of an antenna coil passes through a conductor aperture of a conductive layer, but the magnetic flux does not pass through the conductive layer. Accordingly, the magnetic flux is diverted to a path in which the conductor aperture of the conductive layer is the inside and the outer edge of the conductive layer is the outside. As a result, the magnetic flux passing through the coil aperture of the antenna coil makes a relatively large loop and links the inside and the outside of a coil conductor in an antenna in a communication partner with the antenna apparatus.Type: ApplicationFiled: July 1, 2014Publication date: November 20, 2014Inventors: Noboru KATO, Katsumi TANIGUCHI, Jun SASAKI, Naoki GOUCHI

Patent number: 8842046Abstract: A loop antenna is provided. The apparatus comprises a substrate, a first metallization layer, and a second metallization layer. The substrate has first and second feed terminals and a ground terminal. The first metallization layer is disposed over the substrate and includes a first window conductive region, a first conductive region, a second conductive region, and a third conductive region. The first conductive region is disposed over and is in electrical contact with the first feed terminal; it is also is substantially circular and located within the first window region. The second conductive region is disposed over and is in electrical contact with the second feed terminal; it is also substantially circular and is located within the first window region. The a third conductive region is disposed over and is in electrical contact with the ground terminal, and the third conductive region substantially surrounds the first window region.Type: GrantFiled: July 22, 2011Date of Patent: September 23, 2014Assignee: Texas Instruments IncorporatedInventors: Eunyoung Seok, Brian P.

Publication number: 20140266950Abstract: A directive, instantaneous wide bandwidth antenna is disclosed. The antenna can include a ground plane having a recess with a tapered region accessible by an electromagnetic field via a radiating aperture at a forward end of the recess. The antenna can also include an elongate dielectric feed disposed in the recess. The dielectric feed can have a tapered portion proximate the tapered region to guide the electromagnetic field into the recess through the radiating aperture and influence pattern directivity. The antenna can further include a conductive plating disposed at least partially about the dielectric feed in a wedge configuration to influence pattern beam width. The conductive plating can have a taper to facilitate propagation of the electromagnetic field over a range of frequencies. The conductive plating can be disposed toward a rearward end of the recess relative to the radiating aperture.Type: ApplicationFiled: March 12, 2013Publication date: September 18, 2014Applicant: Raytheon CompanyInventor: Raytheon Company

Patent number: 8786509Abstract: A conformal channel monopole antenna system includes: a housing; a cavity formed within the housing; and a substrate covering the cavity. The substrate includes a first elongated radiating element coupled to two opposing sides of the top surface of the housing at two opposing ends in a first direction; a second elongated radiating element coupled another two opposing sides of the top surface of the housing at two opposing ends in a second direction orthogonal to the first direction; a first feed port at one end of the first elongated radiating element; and a second feed port at one end of the second elongated radiating element. The first elongated radiating element is configured to radiate a first type of polarization and the second elongated radiating element is configured to radiate a second type of polarization simultaneously with the first type of polarization.Type: GrantFiled: March 16, 2010Date of Patent: July 22, 2014Assignee: Raytheon CompanyInventor: Richard S.
