Abstract:
The present disclosure relates to a method and apparatus for varying the directional characteristics of a nonresonant antenna system by varying the impedance of the antenna terminating impedance and, more especially, to making the terminating impedance different from the characteristic impedance of the antenna. Means for interchanging the roles of the ''''feed'''' and ''''load'''' ends of the antenna in order to provide a directivity pattern and its mirror image directivity pattern and means for utilizing this pattern and its mirror image to precisely locate the direction to a transmitting source are also disclosed.
