1. A system comprising:

  • a modifiable mobile communication device including;

    at least two antennas coupled to respective fractional power amplifiers;

    respective returned power detectors coupled to a transmission path between each of the at least two antennas and respective fractional power amplifiers;

    a beamformer unit configured to provide an adaptive beam shaping pattern to the fractional power amplifiers, the adaptive beam shaping pattern configured to shape a transmitted beam pattern to minimize an amount of transmitted power reflected back to at least one of the antennas; and

    a baseband processor configured to provide beam pattern requirements to the beamformer unit;

    wherein the respective returned power detectors provide return loss sampling information to the beamformer unit.
