Abstract
An antenna system responsive to both the E and H fields in a radiated electromagnetic signal relies upon the placement within the influence of a conductive edge formed by an opening in a closed conductive body of an element having an effective electrical length which approximates a resonant length in free space in the intended range of operating frequencies for the antenna.
