Abstract: Systems, devices, methods, computer-readable media, techniques, and methodologies are disclosed for optimizing radio frequency configuration of a user device for better power management and faster time to first fix. The radio frequency configuration of user devices may be optimized based on user input analysis, machine learning, or crowd sourcing methodologies.

Abstract: Antenna structures and methods of operating the same are described. One antenna structure includes a ground plane, a feed point, an antenna element, and a parasitic element. The feed point can be coupled to the antenna element and can receive a signal to cause the antenna structure to radiate electromagnetic energy. The antenna element includes: a first portion that extends in a first direction from the feeding point at the RF feed; a second portion that extends from a distal end of the first portion; a third portion that extends from a side of the second portion; a fourth portion that extends from the third portion; and a fifth portion that extends from the fourth portion. The parasitic element includes: a sixth portion that extends from the fourth portion; and the seventh portion that extends from the sixth portion to the ground plane.

Abstract: Antenna carriers with magneto-dielectric material and beam-shaping elements for enhanced performance and radiation safety of electronic devices are described. One electronic device includes a housing, an antenna element disposed on an antenna carrier, and a printed circuit board (PCB) disposed within the housing, the printed circuit board including radio frequency (RF) circuitry. The antenna carrier can be made up of a plastic cap, a ground plane, and a magneto-dielectric substrate with both dielectric and magnetic properties. The plastic cap is disposed at a first side of the housing and the magneto-dielectric substrate is disposed on a top surface of the plastic cap. The antenna element is disposed on a bottom surface of the magneto-dielectric substrate and electrically coupled to the RF circuitry. The antenna element radiates electromagnetic energy in a resonant mode and the magnetic property of the magneto-dielectric material increase efficiency, frequency bandwidth, or both.

Abstract: An antenna to communicate at a defined frequency; a feed point; and a near-field coupler array coupled to the feed point is described. The near-field coupler array may include a substrate; a ground plane on a first side of the substrate; and a near-field coupler array disposed on a second side of the substrate. The ground plane may include a first aperture and a second aperture. The near-field coupler array can include a first coupler element aligned with the first aperture and a second coupler element aligned with the second aperture. A first width of the first coupler element can be larger than a second width of the first aperture. A third width of the second coupler element can be larger than a fourth width of the second aperture. The first width and the third width can have a correlation to the defined frequency.

Abstract: Devices or apparatuses for changing settings of a neutralization line are described. A radio device may include a neutralization line coupled between a first antenna and a second antenna. The neutralization line has a variable component and the first and the second antennas are electromagnetically coupled and have a first coupling value. The neutralization line is controlled by a controller. The controller is coupled to the first antenna port, the second antenna port and the neutralization line. The controller detects an environmental condition that causes the first coupling value increase to a second coupling value. The controller also adjusts a value of the variable component to change a resistance value or, a reactance value, or both of the adaptive neutralization line to achieve a third coupling value that is lower than the second coupling value.
