PROBLEM TO BE SOLVED: To provide antenna equipment which does not need a taper-shaped amplitude distribution on an antenna aperture and has a low-side lobe characteristic even when the antenna aperture is small in size and the number of antenna elements is small. SOLUTION: In the antenna equipment having a rectangular or a circular aperture shape, a specific part is defined so that a lobe large in radiation amplitude when a radiation element is provided only for the specific part of all over the aperture part may cancel a first side lobe, and radiation elements are provided all over the aperture part except the specific part.
