Abstract: An apparatus includes a first reactive component coupled between a first antenna and a second antenna in a multi-band antenna system. The apparatus further includes a first operation circuit coupled to the first reactive component. The first reactive component and the first operation circuit together form a signal path to enable signal flow between the first and the second antennas when the first and the second antennas are operating at a first frequency. The first operation circuit disables signal flow along the signal path when the first and the second antennas are operating at a second frequency.

Abstract: An antenna for use in portable wireless devices is described for which SAR is significantly reduced relative to conventional antenna designs for the same transmit power. The antenna includes a primary antenna element and one or more parasitic antenna elements. Each parasitic antenna element is electromagnetically coupled to the primary antenna element so as to spread out the RF energy associated with SAR hotspots.

Abstract: This disclosure describes a power unmanned aerial vehicle (UAV) that may generate a current from a magnetic field of an overhead power line. In various implementations, while the power UAV is flying, the power UAV may receive another UAV at a platform. A control element of the power UAV may generate signals to cause the power UAV to fly to a location of a conductor of the power line. The control element may also determine a position of the secondary coil with respect to the power line and generate control signals to adjust the position of the secondary coil based on the determined position of the secondary coil, a determined safety distance, and/or a determined threshold distance for efficient current generation. A shielding substrate may also be provided to shield electronics of the power UAV or other UAVs from magnetic fields.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a radio frequency (RF) including a surface-current dispersing circuit and an antenna structure coupled to the RF feed at a feeding point and coupled to a ground plane at a grounding point. The antenna structure comprises an even multiple of quarter-wavelength elements with a first element coupled to the feeding point and a second element coupled to the grounding point and the grounding point is located at a specified distance from the feeding point. Surface currents, generated as a result of the RF signals being applied to the RF feed at the feeding point, create a first hot spot of an even multiple of hot spots of magnetic field at the feeding point. The surface-current dispersing circuit and the ground point disperse a portion of the surface currents at the feeding point towards the grounding point to create other hot spots of the even multiple of hot spots. The even multiple of hot spots are areas of the antenna structure on which surface-current density is higher than other areas surrounding the areas of the even multiple of hot spots.

Abstract: A low Specific Absorption Rate (SAR) gamma-folded loop-shaped antenna has a resonant structure including two arms connected to an elongated loop and has dual resonant elements in the 5 GHz WiFi band, dividing emissions in the 5 GHz bands between two emission hotspots. The elongated loop folds back upon itself 180 degrees. The antenna also may include a discontinuous transition in cross-sectional area tuned to boost emissions in the 2.4 GHz WiFi band. The antenna is designed for compact handheld devices that may be held close to a person's body, reducing the intensity of energy irradiated into the body in the 5 GHz band by distributing the energy across spatially-separated dual resonant elements.

Abstract: Methods and systems are described for proximity condition detection of a recovery from sensor proximity saturation caused by water immersion of a user device. The device transmits data at a first transmit power level using an antenna. In one system, a proximity condition checker determines that a first proximity sensor and a second proximity sensor are saturated in an unknown state after a power event where the saturation caused at least in part by the presence of water in proximity to the first proximity sensor and the second proximity sensor. The proximity condition checker determines that 1) both the first proximity sensor and the second proximity sensor are no longer saturated and 2) water is no longer in proximity to the first proximity sensor and the second proximity sensor. In response, the user device can transmit data at an increased second transmit power level using the antenna.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a circuit board and an antenna having a ground element disposed on the circuit board. A ground-extension bracket is coupled to the ground element and oriented orthogonally to the circuit board. The antenna further includes a radiating element disposed on the circuit board and oriented linearly with respect to the ground-extension bracket. The antenna, in response to a radio frequency (RF) signal, is configured to radiate electromagnetic energy in a radiation pattern at an angle of polarization with respect to a plane of the circuit board, where the angle of polarization is acute and angled towards the ground-extension bracket.
