摘要： A portable or wearable electronic device can include a device housing defining an internal volume, and an electronic component disposed in the internal volume. The electronic component can be an input component and can have a component housing. The electronic device can also include an antenna feed assembly disposed in the internal volume. The antenna feed assembly can include a conductive grounding component electrically connected to the component housing and the device housing, and an antenna feed component electrically connected to the grounding component and disposed adjacent to the component housing. The conductive grounding component can surround a first major surface and a second major surface of the component housing.

摘要： An antenna for short-range applications, including an elongate two-pole conductor structure with an internal conductor and a sheath conductor coaxially surrounding the internal conductor, and a terminal structure connected to the conductor structure. The terminal structure includes an electrically insulating carrier plate, an electrically conductive sheath conductor connection surface that extends over a first region of the carrier plate on the upper side of the carrier plate and is connected to the sheath conductor, an electrically conductive internal conductor connection surface that extends over a second region of the carrier plate, which is spaced apart from the first region of the carrier plate, on the upper side of the carrier plate and is connected to the internal conductor, an electrically conductive coupling conductor surface that extends over a third region of the carrier plate on the underside of the carrier plate. The antenna provides reliable transmission of information over short distances.

摘要： Provided is a distributor capable of reducing insertion loss while suppressing a ratio in power distribution among output lines from being changed. The distributor 4 is a distributor that is connected with an input line Lin and output lines Lo1 to Lo3 respectively formed on a dielectric substrate 10 as microstrip lines, and distributes to the output lines Lo1 to Lo3 high frequency power fed from a feeding point to a branching point through the input line Lin. In addition, the distributor 4 is configured to include a stub area 42 that is formed in the input line Lin, is separated from the branching point 41, and has a rectangular shape wider than line widths of a first area La and a second area Lb of the input line Lin. The stub area 42 is arranged in a position where the distance d1 between an edge on the feeding point side and lateral edges 3a on an input side of the output lines Lo1 and Lo3 substantially perpendicular to the input line Lin is substantially equal to (λg/4)×(2n+1) where λg is a guide wavelength and n is an integer.

摘要： 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.
