Abstract

(57) Изобретение касается способа смещения лепестка диаграммы направленности антенны в системе связи и приспособления в схеме формирования диаграммы направленности антенны, где используется устройство точной регулировки для формирования из фиксированных лепестков (LF1-LFn) диаграммы направленности антенны интерполированного лепестка с произвольным направлением между этими фиксированными лепестками. Устройство точной регулировки обеспечивает подавление помех.Отчет о международном поиске опубликован 1999.07.08.
