Penrose Tiling Subarrays for Large-Scanning and Energy-Saving Phased Array

A novel partitioning scheme based on Penrose tessellation subarrays has been proposed for phased array design. More in detail, the radiating elements of a phased array arranged on a regular and periodic lattice are grouped into irregularly-shaped tiles by exploiting the features offered by the aperiodic Penrose tessellation. The preliminary results reveal that the novel array architecture ensures a remarkable reduction of the Transmit/Receive modules without compromising the performance in terms of scan angle and peak side lobe level.
