1. A method of transmitting a wideband signal from a high Q antenna comprising:

  • transmitting at a first frequency from the high Q antenna;

    shifting a resonant frequency of the high Q antenna;

    modulating a radiating signal when shifting the resonant frequency;

    switching the high Q antenna to a second frequency, wherein the switching is synchronized with a zero-crossing time of an incident signal to preserve a stored energy during the switching; and

    switching to subsequent frequencies.
