Abstract: A system comprising (1) a tuner configured to tune a radio and (2) a controller communicatively coupled to the tuner, wherein the controller is configured to (1) select a tuner code to apply to the tuner based at least in part on telemetry data indicative of a certain use-case scenario and (2) cause the tuner to tune the radio by applying the tuner code to achieve a certain state of the radio. Various other apparatuses, devices, systems, and methods are also disclosed.

Abstract: The disclosed wireless antenna may include a stratified architecture that electrically isolates an antenna radiating element from a ground plane. For example, the disclosed wireless antenna may be included in a wearable device such that the antenna radiating element is capacitively coupled with the bare skin of the wearer. A slot or cleared volume between the antenna radiating element and the ground plane causes electrical fields to close between the antenna radiating element—effectively enlarged by the bare skin of the wearer—and the ground plane. By clearly separating the antenna radiating element and the ground plane and coupling the antenna radiating element to conductive human tissue, the disclosed wireless antenna significantly improves performance at low frequencies such as LTD low bands. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosed mobile electronic device may include a display, an enclosure supporting the display and comprising a conductive portion, a ground plane positioned within the enclosure, wherein a gap defined between the conductive portion of the enclosure and the ground plane forms a slot antenna that is configured to radiate first electromagnetic signals through a portion of the display, the first electromagnetic signals radiated by the slot antenna being used for wireless communication in a first wireless communication band, and a patch antenna, comprising a substantially planar conductor, that is configured to radiate second electromagnetic signals, the second electromagnetic signals radiated by the patch antenna being used for wireless communication in a second wireless communication band different from the first wireless communication band. Various other related methods and systems are also disclosed.
