Claim 12:
13. A twin beam base station antenna that is configured to split a sector of a three-sector base station into first and second sub-sectors, comprising:
a first array that includes first and second vertical columns of first frequency band radiating elements that are mechanically steered in a first direction in the azimuth plane from an azimuth boresight pointing direction of the twin beam base station antenna, wherein at least some of the radiating elements in the first column are staggered in the horizontal direction from other of the radiating elements in the first column, and wherein at least some of the radiating elements in the second column are staggered in the horizontal direction from other of the radiating elements in the second column; and
a second array that includes third and fourth vertical columns of first frequency band radiating elements that are mechanically steered in a second direction in the azimuth plane from an azimuth boresight pointing direction of the twin beam base station antenna, wherein at least some of the radiating elements in the third column are staggered in the horizontal direction from other of the radiating elements in the third column, and wherein at least some of the radiating elements in the fourth column are staggered in the horizontal direction from other of the radiating elements in the fourth column,
and that are electrically steered further in the first direction,
wherein the first array is configured to form a first antenna beam that provides coverage throughout the first sub-sector, and the second array is configured to form a second antenna beam that provides coverage throughout the second sub-sector.
