Abstract :
An optical beamformer for antenna arrays based on fiber-optical delay lines for feeding subarrays and spatial light modulators to change the radio-frequency phase of independent antenna elements is proposed. The architecture has the potential to control antenna arrays of a large number of elements. Preliminary experimental results to show the feasibility of the concept are provided
