Patent number: 10693218Abstract: An apparatus is provided with a conductive bezel section and a conductive ground plane section forming a perimeter and being positioned opposite the conductive bezel section. The conductive ground plane section is separated from the conductive bezel section by a perimeter gap at the perimeter. A structural tank circuit is integrated with and connecting the conductive bezel section and the conductive ground plane section across the perimeter gap. Another implementation may include a structural capacitor or a structural inductor integrated with and connecting the conductive bezel section and the conductive ground plane section across the perimeter gap.Type: GrantFiled: October 17, 2014Date of Patent: June 23, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Sidharath Jain, Nil Apaydin, Javier R. De Luis, Ben Shewan, Alireza Mahanfar, Paul O'Brien

Patent number: 9799953Abstract: A wireless radio communication device includes a printed circuit board, a plurality of antennas formed on the printed circuit board, and one or more out-of-plane isolation elements conductively coupled to a ground plane of the printed circuit board. Each antenna extends in a reference plane or in a plane parallel to the reference plane. Each out-of-plane isolation element extends in a direction transverse to the reference plane. Each antenna of the plurality of antennas is configured to resonate in a selected radio frequency (RF) band. The one or more out-of-plane isolation elements are configured to conduct a current in response to excitation of one or more associated antennas that contributes to at least partially cancelling an RF transmission coupling between the one or more antennas and one or more other antennas of the plurality of antennas.Type: GrantFiled: March 26, 2015Date of Patent: October 24, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Nil Apaydin, Javier R. De Luis, Benjamin Shewan, Mark William Casebolt

Patent number: 9601824Abstract: An electronic device case includes a conductive cap section and a conductive bezel section forming a perimeter outside the conductive cap section and separated from the conductive cap section by a bezel gap. A conductive ground plane section forms a perimeter and is positioned opposite the conductive cap section and the conductive bezel section. The conductive ground plane section is separated from the conductive bezel section by a perimeter gap. One or more components reside between the conductive cap section and the conductive ground plane section forming a resonant cavity including a ground plane resonant cavity portion between the one or more components and the conductive ground plane section and a substantially annular resonant cavity portion between the one or more components and the perimeters of the conductive bezel section and the conductive ground plane section.Type: GrantFiled: October 17, 2014Date of Patent: March 21, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Nil Apaydin, Paul O'Brien, Javier R.

Patent number: 9203144Abstract: Multiband antenna decoupling networks and systems including multiband antenna decoupling networks are provided herein. A multiband decoupling network is connected to two or more closely spaced antennas. The multiband decoupling network includes lumped components and is reconfigurable to decouple the two or more antennas at a plurality of distinct communication frequency bands. The multiband decoupling network may include tunable lumped components and be reconfigurable through tuning the tunable lumped components. A pi network may be used for the multiband decoupling network. At least one separate impedance-matching network may also be used to match the input impedance of the multiband decoupling network to the output impedance of transmission lines leading to the multiband decoupling network.Type: GrantFiled: December 6, 2012Date of Patent: December 1, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Javier R.

Publication number: 20140347232Abstract: Antennas, antenna systems, and electronic devices containing antennas are described herein. Non-antenna components of electronic devices can be used as an antenna, as a portion of an antenna, or as part of a feed path from a transceiver output to an antenna. An output of a transceiver can be coupled to a conductive portion of a non-antenna component through a feed point. Conductive portions of the non-antenna component can serve as an antenna for the transceiver. An additional conductor can also be coupled to the output of the transceiver. The additional conductor, the conductive portions of the non-antenna component, or the combination of the additional conductor and the conductive portions of the non-antenna component can act as an antenna for the transceiver.Type: ApplicationFiled: May 21, 2014Publication date: November 27, 2014Inventors: Alireza Mahanfar, Nil Apaydin, Javier R. De Luis, Rod G. Fleck, Benjamin Shewan
