Abstract

PURPOSE:To enable radio waves of several frequencies of a multi-beam scanning antenna to scan independently by providing a 2nd primary radiator with an adjusting method. CONSTITUTION:To the radio-wave path between 1st primary radiator array antenna 3'' and reflex mirror 2, 2nd primary radiator array antenna 3' is provided which has radiation elements 11 to 11'. Radial beam 5''' from this antenn 3'' is reflected by antenna 3'' with phase shifters 12 to 12' which can change the radial beam direction freely to obtain beam 5, which changes into beam 5'' through mirror 2 and main reflex mirror 1. At this time, the beam direction of antenna 3'' is changed by phase shifters 15 to 15' to change the incident angle to antenna 3' and, consequently, the direction of beam 5'', so that a beam scan will be made. Several antennas of the same constitution as above-mentioned antenna 3' are provided and a radio wave of a different frequency from each antenna is excited, so that a beam of each frequency can be made to scan independently.
