A process for the widening of the radiation pattern with an antenna array elements distributed in a volume

摘要

The present invention relates to the electronic scanning antenna arrays, the radiating elements are distributed inside a volume instead of being distributed on a reflective surface of revolution. It relates to a process in order to widen the beam of an antenna pointing in a direction without hindrance to be asymmetrical deformations or to considerably increase the secondary lobes. This method consists in applying to the radiating elements of the antenna to steric a law of excitation of the phase for each radiating element of index n, the value: & br / (see appended drawing in bopi) & br / which is the wavelength of the radiation emitted or received and rhon the distance of the radiating element of the index n is considered to a point 1 outside the steric antenna located on the axis of the aiming direction of the side opposite to the aiming direction.
