Classification description:

Arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an antenna or antenna system varying the relative phase or relative amplitude of energisation between two or more active radiating elements; varying the distribution of energy across a radiating aperture; Array of radiating elements provided with a feedback control over the element weights, e.g. adaptive arrays; Means for null steering; Adaptive interference nulling; Combination of a main antenna unit with an auxiliary antenna unit the auxiliary unit being composed of a plurality of antennas being secundary elements, e.g. reactively steered
