Provided is a reflect array that enables reflectance at a plurality of angles of incidence while maintaining a high gain without causing a decrease in the electric field intensity of a reflector plate, and that can simplify the installation of the reflect array. In the reflect array, a plurality of first elements and a plurality of second elements are arranged on XY plane. The first elements are arranged in Y direction to form a first row of elements. The second elements are arranged in Y direction to form a second row of elements. The first element rows and the second element rows are alternately arranged in X direction. The two angles of maximum reflectance are on the same positive or negative side of X-axis.

An array antenna having multiple elements transmits and receives electromagnetic waves via the elements. The array antenna has an electromagnetic wave control unit that inclines direction of transmission and reception of electromagnetic waves in at least a first direction by emitting electromagnetic waves of mutually different amplitudes or phases at the elements. The array antenna has multiple element columns having two or more N elements aligned at a prescribed interval din a second direction substantially orthogonal to first direction. The element columns are configured as subarrays. The elements are arranged with a prescribed interval dtherebetween in the first direction to form element rows, and the element columns are disposed offset in first direction by approximately d/2 from elements or element columns adjacent thereto in second direction. The element column in the outermost element row has more elements than any other element column in the element row other than the outermost element row.
