Technology for ultra broadband reconfigurable beamformer and front-end

This paper gives an overview of research results from FOl on integrated beamforming components and front-end for ultra wideband phased array. The feasibility of a flexible, wideband antenna array with frequency independent features has been demonstrated. Two objectives are to enable adaptation of beamwidths to different requirements, and to enable a frequency independent beamwidth over a wide frequency range. MMIC true-time delays and reconfigurable active power distribution working in the 2-18 GHz range are also presented.
