1. An antenna integrated into the surfaces of an airfoil structure having a leading edge and opposed side surfaces tapered rearwardly toward a trailing edge comprising:
a first metallized area extending about the a leading edge of the airfoil and along a majority portion of the side surfaces of said airfoil;
a second metallized area extending about the a trailing edge of the airfoil and along a minority portion of the side surfaces and spaced from said first metallized area by a first gap, said first gap being configured to provide a capacitive coupling between said first and second metallized areas; and
a third metallized area disposed on a cap portion of the airfoil and spaced from said first metallized area by a second gap and electrically connected in series with said first and second metallized areas and formed with at least one tuning gap extending between the opposed side surfaces.
