An improved communication system and method employing an actively controlled antenna array architecture is disclosed. The array (10) contains a plurality of driven radiating elements that are spatially arranged having a pair of radiating elements (112, 114) fed with an RF signal predistorted so as to provide a controlled variation of the antenna array's elevation radiation pattern. High power amplifier (PA) efficiency is maintained by adaptive predistortion, coupled to each high power PA (140, 142), while providing beam tilt and side lobe control. |
