1. An electronic device, comprising:

  • a. a transceiver;

    b. a first transmission line coupled to the transceiver;

    c. a first antenna characterized for operation in at least a first bandwidth coupled to the first transmission line, the first antenna having at least a first impedance in an unloaded state and a second impedance in a loaded state;

    d. a second transmission line coupled to the transceiver; and

    e. a second antenna characterized for operation at least in a second bandwidth coupled to the second transmission line;

    wherein when the first antenna transitions from the unloaded state to the loaded state, power to the second antenna increases.
