Abstract
Mathematical model of multibeam antenna radiation field with helical feed is presented. Some results of radiation field modeling are given, as well as estimation of effective zone on reflector surface is performed. Value overlapped zones influence, which are created with adjacent feeds, on characteristics of reflector antenna radiation is shown. The minimal accessible angle value between radiators is shown. Maximal angle limits of feed scanning, which prevent characteristics of reflector antenna radiation from distortion.
