Paper Abstract

The increasing need for rapid steering of antenna beams has prompted significant research and development efforts in phased-array technology. Advances in solid-state power amplification now make it possible to construct arrays with individual amplifiers at each radiating element. Consequently, the power loss in the beam-forming network is greatly reduced, since it operates in the low-power regime. Traditionally, beam-forming and steering are performed by individually controlled phase shifters and variable gain amplifiers in the signal path of each array element. Waveguide power splitters distribute the signals to the input ports of the antennas.
