摘要
Among other things, a reconfigurable antenna array (RAA) includes individual pattern reconfigurable antennas (PRA). Each of the PRAs has (a) an antenna, (b) components controllable to generate and effect any of two or more modes of the PRA, the modes having respectively different steered radiation patterns, and (c) inputs to receive drive signals for the antenna and control signals for the controllable components. Control circuitry has outputs coupled to the inputs of the PRAs to drive the antennas of the PRAs to form an array beam having an array peak in a particular direction and at the same time to deliver control signals for the controllable components to effect a selected mode of each of the PRAs for which the steered radiation pattern has a peak in the particular direction of the array beam and has one or more nulls in the directions of one or more of the side-lobes of the array beam.
