Abstract

The development of a phased array conformal antenna system of cylindrical geometry, operating at 10 GHz, is presented. A beamforming unit, implemented in the framework of the proposed system, suitably adjusts antenna element phases at IF stage. The phases at the receiver and transmitter chains are determined by using least squares pattern synthesis technique, while excitation amplitudes are taken to be constant. The obtained antenna radiation patterns provide steerable main lobes and nulls at predefined directions, including control of the side lobes at specified levels
