Abstract: In a disclosed method, a computing device receiver, from a wireless receiver (RX), first data indicative of channel properties of a first communication link between the wireless receiver (RX) in a first device and a wireless transmitter (TX) in a second device. The first device and the second device are located in a building. The computing device further executes a neural network to process the first data to distinguish humans from stationary objects within the building and detect presence of the human in the building. The computing device transmits result data indicative of the presence to at least one of the first device or the second device.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a single radio frequency (RF) feed and a folded monopole element coupled to the single RF feed. The folded monopole element is an integrated WAN/GNSS antenna that receives electromagnetic energy in a first frequency band and receives electromagnetic energy in a second frequency band. The first frequency band is a wireless area network (WAN) frequency band and the second frequency band is a global navigation satellite system (GNSS) frequency band. The apparatus further includes an impedance matching circuit coupled to the single RF feed. The impedance matching circuit includes a diplexer to extract out GNSS frequency signals received by the folded monopole element from WAN signals received by the folded monopole element.

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: 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: Techniques are described for dynamically tuning mobile device antennas. Input derived from multiple sources and representing a variety of scenarios is provided to the RF modem of a mobile device. The modem is configured to select antenna tuning settings based on this input, each of which tunes the antenna by modifying its impedance as appropriate for the corresponding scenario.
