Since the weighting coefficient associated with each antenna is a complex number, both magnitude and phase controls are required in analog implementation and they are different for different antennas. This will add complexity to its implementation especially for large-scale antenna arrays and this problem can be mitigated by phase-only control on the analog beamformer. Here a novel design is proposed based on the work in [1], where a phase-only control is considered so that the magnitude of weighting coefficients can be precomputed by the designers in advance according to their specified requirements.
