POLARIZATION DIVERSITY ARRAY ANTENNA DEVICE

PROBLEM TO BE SOLVED: To prevent deterioration of an inter-polarization coupling amount characteristic and a cross polarization characteristic by correcting irregularity of a polarization face.SOLUTION: In this polarization diversity array antenna device, plural polarization diversity antenna units (10) having a first dipole antenna element (AE1) for +45-degree polarization and a second dipole antenna element (AE2) for -45-degree polarization crossing with each other on the same surface are aligned in a vertical direction at a predetermined interval, and a reflector plate (60) is arranged on the backs of the polarization diversity antenna units (10). Adjusting conductor parts (27, 28) for correcting irregularity of a polarization face are formed on element conductors constituting the first dipole antenna element (AE1) and element conductors constituting the second dipole antenna element (AE2), respectively.
