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.

Abstract: An electronic device that includes a metal element arranged to at least partially cover a high impedance region associated with an antenna of the electronic device. The metal element presents a capacitive load to the antenna to mimic or replicate a capacitance placed on the antenna by a conductive element, such as a user's finger, coming in contact or close proximity to the antenna area. The capacitive load applied by the metal element tunes the antenna system for a large capacitance to resist antenna de-tuning and radio link interruption caused by the unintended user contact or near contact with the high impedance region of the antenna.

Abstract: A groundless radio frequency (RF) test probe comprises a first connector to receive a signal from a system under test and a second connector to present the signal as an output. The probe further comprises an antenna array coupled between the first connector and the second connector, the antenna array to couple the signal from the first connector to the second connector, wherein the antenna pair is impedance matched with the system under test. The probe does not have a physical ground connection with the system under test.

Abstract: The present disclosure can provide a wideband antenna with a folded monopole structure that operates at GPS frequencies and high band (HB) frequencies. Accordingly, the wideband antenna can function as an integrated GPS and HB Diversity antenna for a computing device. In some embodiments, due to various constraints, the antenna can be designed to have a curved structure to fit within a corner of the computing device. The folded monopole antenna can comprise two substantially parallel conducting arms, which improves antenna performance. In some embodiments, the present disclosure can provide GPS and high band impedance matching for a signal received from the antenna in order to improve/ensure signal quality. The signal can be decoupled into a GPS signal portion and a high band signal portion for additional processing and/or information retrieval.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One wearable electronic device includes a housing of conductive material and an antenna structure disposed on or within a band that is used to affix to a user. The antenna structure includes a first connector, a second connector, and a first antenna element. The first and second connectors extend out from sides of the band and electrically couple to a RF feed and a ground point when the first and second connectors are physically coupled to the housing. The RF circuitry is operable to cause a first current flow on at least the first antenna element via the first connector to radiate electromagnetic energy in a first frequency range.
