PROBLEM TO BE SOLVED: To constitute a small-sized polarized wave diversity antenna simply even if it is of three-dimensional structure. SOLUTION: The first substrate 2 for horizontally polarized waves where an H-type element 5 for sending and receiving horizontally polarized waves is printed on its one side, and the second substrate 3 for horizontally polarized waves where an H-type element 15 for sending and receiving horizontally polarized waves is printed on its one side, are combined roughly orthogonally. A substrate 4 for vertically polarized waves where a vertical element for sending and receiving vertically polarized waves is printed is fixed axially to one side of the second substrate 3 for horizontally polarized waves. Then, the tops of the first substrate 2 for horizontally polarized waves and the second substrate 3 for horizontally polarized waves are fitted in the grooves made in a top circular substrate 6, and the bottoms are fitted in the grooves made in a bottom circular substrate 7.
