Abstract :
A novel Lossless Beam-Forming Network (BFN) architecture for Limited Field of View and Multi-Beam linear arrays is introduced. The BFN is based on the Overlapped Sub-Array technique and allows a substantial reduction in the number of control elements and associated active devices (i.e. amplifiers, variable phase shifters, etc.). This advantage is achieved adopting a lossless topology with reduced implementation complexity.
