<P>PROBLEM TO BE SOLVED: To suppress a grating lobe in a reflect array which reflects an incident wave in a desired direction. <P>SOLUTION: A reflect array comprises at least first and second element arrays which are adjacent to each other, and each of the first and second element arrays includes a plurality of elements. A phase difference of radio waves reflected by two elements belonging to one element array between the first and second element arrays is proportional to a product of an interval between the two elements and a value of a trigonometric function with a reflection angle of a radio wave as an argument, the total of phase differences over all the plurality of elements belonging to one element array corresponds to 2π, and a phase of a radio wave reflected by any element belonging to the first element array is also different from the phase of a radio wave reflected by any element belonging to the second element array. <P>COPYRIGHT: (C)2013,JPO&INPIT |
