Abstract
Disclosed is an antenna device in which an excitation phase changing unit () for changing the excitation phases of element antennas (-) to (-) by controlling phase shifters (-) to (-) dependently on preset phase values is disposed, and every time the excitation phases are changed by the excitation phase changing unit (), a radiation pattern forming unit () shifts the phases of a sum signal and a difference signal, and forms a monopulse sum pattern by time-integrating the sum signal after phase shift and also forms a monopulse difference pattern by time-integrating the difference signal after phase shift.
