A Phase-only Pattern Synthesis Method for Large Satellite Array Antenna

This paper focuses on the problem of minimizing the maximum side lobe level (SLL) for a given secondary amplitude distribution by phase-only control. A novel fitness function based on particle swarm optimization (PSO) algorithm is introduced to optimize the phase of the excitation. Eamples of beam pattern synthesis for large planar phased array are presented, and simulation results verify the effectiveness of the design. Indeed, it has a good robustness in amplitude and phase errors.
