Antenna array with reconfigurable antenna array geometry

A controller for operating an antenna array, the antenna array comprising antenna elements and having a reconfigurable antenna array geometry, the controller comprising processing circuitry, the processing circuitry being configured to cause the controller to:

• apply, as part of operating the antenna array for performing wireless communication, at least two antenna array geometries at the antenna array in which:
• (i) the at least two antenna array geometries are alternatingly applied when the antenna array is operated, at least two of the at least two antenna array geometries being cyclically applied when the antenna array is operated, the cycling arranged to avoid having a side lobe positioned in at least one radiation direction;
• (ii) each of the at least two antenna array geometries has a respective radiation pattern having a main lobe and a set of side lobes;
• (iii) the main lobes of all the radiation patterns have same pointing direction;
• and
• (iv) pointing directions of the side lobes differ between the radiation patterns of the at least two antenna array geometries.
