Abstract
An antenna device of the type including an array antenna comprised of a plurality of planar antenna elements, wherein the planar antenna elements are arranged in a staggered pattern such that two adjacent ones of the antenna elements are disposed diagonally with each other. With this staggered arrangement, the spacing between the adjacent antenna element becomes larger than that in a conventional matrix arrangement, whereby the interference between the adjacent planar antenna elements is considerably reduced, while the antenna efficiency of the planar antenna elements is improved.
