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.

Abstract: Techniques for harmonizing wireless communications performed by a computing device which communicates using varying wireless communication standards are described herein. For instance, a computing device may include multiple chipsets with associated antennas that are configured to perform wireless communications using separate wireless standards which operate at overlapping frequencies. To avoid performance degradation experienced in simultaneous use cases with communications operating at overlapping frequencies, the multiple chipsets may be configured with logic to determine which communications are prioritized when multiple chipsets attempt to communicate simultaneously. The multiple chipsets may be communicatively coupled to coordinate their communications by prioritizing certain types of communications over other types of communications to avoid simultaneous communications in overlapping frequencies. In this way, multiple chipsets that communicate using different standards at overlapping frequencies may avoid performance issues experienced in simultaneous use cases, while performing the communications which are of a highest priority level.

Abstract: Antenna structures and methods of operating the same are described. An antenna structure may include an antenna carrier, a first antenna disposed on the first antenna carrier and coupled to a first radio frequency (RF) feed, a second antenna disposed on the first antenna carrier and coupled to a second RF feed, a third antenna disposed on the first antenna carrier and coupled to a third RF feed, and a fourth antenna disposed on the first antenna carrier and coupled to a fourth RF feed. The first antenna and the second antenna may be located along a first axis of the antenna carrier that passes through a center of the antenna carrier. The third antenna and the fourth antenna may be located along a second axis of the antenna carrier that passes through a center of the antenna carrier.

Abstract: An adaptive envelope tracking calibration module executes a routine to calibrate a radio frequency (RF) transmitter in a communication device comprising an envelope tracking system. The routine includes receiving a selection of a calibration target power that is greater than a desired output power of the RF transmitter and determining an output power estimate for the power amplifier as a supply voltage for the power amplifier varies according to an output of the envelope tracking system. The routine further includes adaptively adjusting the calibration target power when the output power estimate is not greater than the calibration target power.
