Abstract: The range of a Near Field Communications (NFC) in an electronic device is boosted by positioning a magnet near the center of a spiral loop NFC antenna. The magnet interacts with a modulated magnetic field generated by the antenna, concentrating the power of the modulated field. The magnet may be part of another component of the device, such as a magnet in the zoom mechanism of a camera. If the electronic device has a metal case, performance of the NFC antenna is further enhanced by including an opening through the metal over an axis of the magnet and a segment of the antenna's spiral loop, and by extending the opening to eliminate a parasitic current pathway around the antenna. The extended opening in the metal case significantly reduces the effect of eddy currents generated in the housing that counter the NFC magnetic field.

Abstract: A user device obtains sensor data from sensors included in the user device. A set of current state information is determined based on the sensor data. A tuner code associated with the current state information is identified. Tuning values associated with the tuner code are varied during a training stage to determine an optimized tuner code. One or more antennae of the user device are tuned for communication in accordance with the optimized tuner code.

Abstract: An electronic device including a Near Field Communication (NFC) antenna and a slot antenna is described. The slot antenna may be formed by a slot opening in a housing of the electronic device. The slot opening may be shaped as a rectangular slot, a T-shaped slot, or T-shaped slot leading into a circular opening. The slot opening exposes the NFC antenna and allows the NFC antenna to radiate in a first frequency band while the slot antenna radiates at a second frequency band.

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.
