A NEW CLASS OF COPHASAL ANTENNA-ARRAYS WITH SIMPLE COMPACT FEEDS

The problem of synthesis of the given shape contoured directivity patt ern of spacecraft hybrid antenna with purpose of uniform ''illuminatio n'' of the some territorial zone is considered. The variational formul ation of the synthesis problem according to the given magnitude patter n is used. The mean-square deviation of given and synthesized magnitud es is chosen as optimization criterion. It permits to improve the appr oximation quality of the magnitudes, to influence by a certain mean on polarized properties of synthesized directivity patterns, and also to satisfy set additional requirements. Examples of synthesis of the con toured directivity patterns, which covers uniform the given territory are presented. In these examples, the hybrid antenna consisting of the rectangular cutting from a parabolic reflector and flat feed array is used.
