Abstract

PURPOSE:To realize an antenna having dual beams by one feeding horn, by providing grooves on a main reflecting specular surface. CONSTITUTION:On a main reflecting specular surface 7, grooves 9 perpendicular to the center section are provided, thereby obtaining periodical phase distribution over an opening. At this time, only the phase is controlled by the grooves 9 and to be concrete, the directions of beams, a mutual amplitude ratio, and a phase difference are adjusted to set the phase.
