Abstract :
A four-element W-band linear array with photonic true-time delay beam steering is presented. The array demonstrates the necessary technology leading towards an integrated two-dimensional photonically steered array. Because the antenna elements are photonically fed, only the amplifiers and photodiodes need to be local to the aperture, with all other associated hardware remoted. Wideband operation is demonstrated, showing operation from 75-100 GHz, and beam steering from 84-100 GHz.
