The voltage feed of a three-dimensional structure and the far field pattern, related by a single operator

Presents a circuit type approach for the relation between a three dimensional radiating antenna or array and its far field radiation pattern, using only one matrix to connect directly the feed distribution and the far field pattern. With this procedure not only the far field radiation pattern calculations for different feed configurations are made much more easy than the usual two step procedure, but also it is possible to perform the synthesis, a situation that is not present in the classical approach. This was made possible by applying the digital signal processing techniques to deal with the radiation pattern of antennas or arrays
