Space-wave phase-shifting array

An apparatus comprising:

• a reconfigurable antenna array comprising
• a plurality of emitting antennas,
• a plurality of drive inputs corresponding to respective emitting antennas of the plurality of emitting antennas and configured to receive drive signals for the respective emitting antennas,
• a plurality of controllable components that are controllable to perform space-wave phase shifting on radiation emitted by the plurality of emitting antennas, and
• a plurality of control inputs corresponding to the plurality of controllable components, the plurality of control inputs arranged to receive control signals for the plurality of controllable components;
• and
• control circuitry having outputs coupled to the plurality of drive inputs and the plurality of control inputs, the control circuitry configured to
• drive the plurality of emitting antennas to generate the radiation,
• deliver the control signals to the plurality of controllable components to cause the plurality of controllable components to space-wave phase shift the radiation emitted by the plurality of emitting antennas, the space-wave phase shifting by the plurality of controllable components causing the reconfigurable antenna array to emit a beam having an intensity peak in a target direction.
