Abstract: A processing device tracks a frequency hopping sequence implemented by a personal area network (PAN) transmitter in a user device and identifies a set of filter coefficients corresponding to a first frequency of a plurality of frequencies in the frequency hopping sequence, wherein the PAN transmitter is currently transmitting a PAN signal at the first frequency. The processing device configures a tunable notch filter with the set of filter coefficients to cause the filter to remove at least a portion of a PAN component at the current frequency from a combined signal received at a wireless local area network (WLAN) receiver in the user device, the combined signal comprising a WLAN component attributable to a received WLAN signal and the PAN component attributable to the PAN signal.

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: Antenna structures and methods of operating the same of a wideband dual-arm antenna of an electronic device are described. One wideband antenna includes a first feeding arm coupled to a radio frequency (RF) feed and a second feeding arm coupled to the RF feed. At least a portion of the second feeding arm is parallel to the first feeding arm. The wideband dual-arm antenna further includes a third arm coupled to the ground plane. The third arm is a parasitic ground element that forms a coupling to the first feeding arm and the second feeding arm. The parasitic element increases a bandwidth of the wideband antenna.

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: 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.
