Abstruct-A techniquebasedonarecentpaper [3] for designing
shaped dual reflector antennas that appears to be significantly better
than the traditional method[I], [2]is presented. The main advantages
derived areextreme computational simplicity and the ability to utilize
very accurate feed pattern expressions.A typical practical problem is
solved using [l]and our method to bring out these features.
The analytical procedure for determining the reflector pro-
