Patent number: 11824263Abstract: A system includes a first antenna and a second antenna. The first antenna includes an antenna section. The antenna section includes a first antenna segment, a second antenna segment adjacent to the first antenna segment, and a notch circuit disposed within a notch between the first antenna segment and the second antenna segment. The notch circuit prevents a first frequency of a signal from passing from the first antenna segment to the second antenna segment while allowing a second frequency from the signal to pass from the first antenna segment to the second antenna segment. The second antenna is disposed proximate to the first antenna. The first antenna occupies a second near field region of the second antenna and the second antenna occupies a first near field region of the first antenna.Type: GrantFiled: May 17, 2022Date of Patent: November 21, 2023Assignee: IXI Technology Holdings, Inc.Inventors: Daniel Hyman, Byron del Castillo, William Herbert Darden

Publication number: 20150341476Abstract: An electronic device having a unique interface between the electronic circuitry of the device and an antenna that is external to the device and located in a band. The antenna functionality is achieved externally in the band and includes a conductive path from one or more components of the device to the antenna in the band. The conductive path may extend through an exterior housing of the device to electrically connect the one or more components and the antenna.Type: ApplicationFiled: January 4, 2013Publication date: November 26, 2015Inventors: Kenneth Hogue, Owen Lewis Joyce, Timothy Bodnarchuk, Jeffrey Lick, Torbjørn Anderssen, Sten Kirkbak, Pål Selnæs, Anders Broms, Espen Voll, William Herbert Darden, IV
