PROBLEM TO BE SOLVED: To adopt a configuration possible for miniaturization for a polarized wave diversity antenna even when it is designed for a low frequency. SOLUTION: A horizontally polarized wave use H type element 10 consists of a 1st H type element 11a and a 2nd H type element 11b of an H shape where linear vertical elements 12a, 12b (12c, 12d) are provided at both ends of a linear feeding element 13a (13b) placed horizontally. Since the 1st H type element 11a and the 2nd H type element 11b are placed within a horizontal plane at an angle difference of about 90 degrees and receive power at a phase difference of about 90 degrees, the polarized wave diversity antenna is omnidirectional within the horizontal plane. A linear vertically polarized wave use dipole element 20 is placed in the vicinity of the horizontally polarized wave use H type element 10 to configure the polarized wave diversity antenna 1 smaller in size.
