Abstract :
A preliminary study on the performance of wideband limited-field of view (LFOV) arrays consisting of overlapped subarrays has been performed to pursue a reduction in the number of controls. Beam-squinting and beamforming losses will be addressed as a function of both frequency and scan angle.
