After passing the phase shifter, the light reaches the radiator. light from each radiators interfere, forming beams at various angles. Diffraction occurs, which is similar to the double slit. And using the strongest beam among them, beam-scanning is performed in the desired direction. With this technique we have made a small sized OPA that can steer 45 degrees in transversal angle.
