Abstract
A 45 degree polarization diversity antenna having improved beamwidth characteristics. The antenna includes a plurality of dipole sub-arrays each sub-array comprising four dipole elements arranged in a diamond shape. Two dipole elements in each sub-array are arranged at an angle of approximately plus 45 degrees from the earth's surface to form a plus 45 degree polarized dipole element array and the other two dipole elements are arranged at an angle of minus 45 degrees from the earth's surface to form a minus 45 degree polarized dipole element array. The dipole elements are arranged such that the phase centers of one plus 45 degree dipole element and one minus 45 degree element line up along a first substantially vertical line and the phase centers of the remaining plus 45 degree and minus 45 degree dipole element line up along a second substantially vertical line.
