  • Antenna for providing a dielectrically induced, directionally dependent radiation pattern phase shift
    Patent number: 3946396
    Abstract: An antenna for providing a radiation pattern in which the phase of the emitted electromagnetic waves varies with direction from the antenna. The emitted electromagnetic waves propagate through a region, associated with the antenna, having dielectric properties which are a function of the direction of propagation. The varying dielectric properties result in a direction-dependent phase shift for the emitted electromagnetic waves. By providing a reference radiation pattern having a phase-shift independent of direction, the direction from the antenna can be determined by comparison of the phases of the reference and of the direction-dependent electromagnetic waves.
