1. An antenna array comprising:
- an adjustable array of radiator elements arranged in a plurality of columns; and
a reflector comprising a center reflector panel and first and second outer reflector panels wherein the first and second outer reflector panels each comprise a level plane,the adjustable array of radiator elements comprising at least one first radiator element movably coupled to the first outer reflector panel, and at least one second radiator element movably coupled to the second outer reflector panel, and at least one third radiator element rigidly attached to the center reflector panel,wherein a first of the at least one first radiator element and a first of the at least one second radiator element are spatially adjustable relative to a first of the at least one third radiator element, to alter a radiation pattern of the antenna array.

Abstract
A tri-column antenna array architecture, containing a plurality of active radiating elements that are spatially arranged on a modified reflector structure is disclosed. Radiating elements disposed along (P1 and P2) outlying center lines are movable and provided with compensating radio frequency feed line phase shifters so as to provide broad range of beam width angle variation of the antenna array'"'"'s azimuth radiation pattern.
