ABSTRACT:
A directionally sensitive receiving antenna, particularly for microwave radiation, utilizes the change in impedance, as a function of the angle between the energy vector of incident radiation on a gyrotropic medium, e.g. a ferrite material, and a magnetic field passing through the medium, enabling a highly directional antenna of small physical dimensions to be constructed.
