design and technique of multimodal networks as beams for multifascio to reflector antennas.

摘要

system of antenna beams partially overlapping, consisting mainly of a reflector, an array of radiation sources and the trainer of the beam.in which configuration is the most original aspect of the invention, it is double waterfallelement that allows you to use all the degrees of freedom available in the optimization of excitation coefficients of elements radians.namely, in making the optimization of these coefficients in the system reflector "feeds" where there are two or more aliases overlap must impose the constraintof orthogonality between the sets of optimized each excitation for each different coverage.the invention is in the field of electronics for the antennas, particularly in the field of space applications.
