<P>PROBLEM TO BE SOLVED: To provide a multibeam reflect array capable of reflecting an incident radio wave to desired multiple directions. <P>SOLUTION: A multibeam reflect array includes two or more element arrangements each including a plurality of elements aligning along a predetermined direction. In each of a first element group and a second element group included in at least one of the element arrangements, a phase difference between radio waves reflected by two elements is proportional to the product of the distance between the two elements and the trigonometric function value with respect to the reflection angle of the elements, and the distance between the adjacent elements in the first element group is equal to a rational multiple of the distance between the adjacent elements in the second element group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
