AB - The radiation pattern of the primary feed is developed in a set of elliptical gaussian beams (Egb). Each of them has a limited spatial intersection with the reflector. Under several conditions, any incidentEgb creates a reflected beam which is also anEgb and its parameters can be computed directly. The antenna pattern is achieved by summing all the reflectedEgbS. Such operations require shortCpu time (100 seconds typically on aHa Pa 9000/735 workstation).In the proposed paper, we expose the basic principles and key elements of this method in four points. The first one describes the decomposition of the incident field on a set ofEgb. The second point is the use of improvedEgbS with respect to the paraxial approximation to get stabilized radiation pattern in the far field. The third chapter is related to the interaction of an elementary beam with the reflector. Lastly the radiated field is calculated, at any point of space, as the vectorial superposition of the reflectedEgb. This method allows to obtain the radiated field from the near zone to the remote zone with a similar accuracy in a very short time.
