Abstract
The disclosure relates to electronic scanning array antennas whose radiating elements are distributed within a volume instead of being distributed on a reflective surface that is plane or generated by revolution. It pertains to a method for broadening the beam of a volume antenna aimed in a direction without giving it asymmetrical deformation or substantially increasing the secondary lobes. This method consists of applying the following phase excitation law to the radiating elements of the volume antenna: ##EQU1## where .lambda. is the wavelength of the radiation transmitted or received and .rho..sub.n is the distance from the radiating element with an index n considered to a point I external to the volume antenna located on the axis of aiming direction on the side opposite the aiming direction.
