This project focuses on the design of beamforming networks for linear array applications. To achieve low loss and low sidelobe beamforming characteristics, a variety of antenna array patterns and power dividing schemes were studied. The study on the antenna array includes Binomial array, Dolph-Chebyshev array, Taylor array, Cosine on Pedestal array and so on. The study on the power divider was mainly focused on stripline structures.
