1. Electronically signal direction oriented antenna means comprising, in combination:

  • ground plane means;

    driven element means mounted on said ground plane means;

    a plurality of parasitic elements, each of equal length and having a base portion juxtaposed said driven element means and mounted at the base portion on said ground plane means; and

    selector means, connected to one end of each of said parasitic elements below said ground plane means, for electrically and selectively altering the impedance at the base portion of said parasitic elements from director to reflector means by changing the impedance from capacitive to inductive while maintaining the same mechanical radiating length.
