1. A multi-beam cellular communication antenna, comprising:
an antenna array having a first row of radiating elements that includes at least two radiating elements that are spaced apart from each other in a row direction and a second row of radiating elements that includes at least three radiating elements that are spaced apart from each other in the row direction, the first row separated from the second row in a column direction that is perpendicular to the row direction,
wherein adjacent radiating elements in the first row are spaced apart from each other by a first distance in the row direction and adjacent radiating elements in the second row are spaced apart from each other by a second distance in the row direction, the second distance being different from the first distance.
