摘要：
The present invention relates to a system for changing the radiation pattern shape of an antenna array during electrical tilting. The antenna array has multiple antenna elements, and the system comprises a phase-shifting device provided with a primary port configured to receive a transmit signal, and multiple secondary ports configured to provide phase shifted output signals to each antenna element. The system further comprises a phase-taper device that changes phase taper over the antenna elements, and thus the beam shape, with tilt angle θ. The invention is adapted for use in down-link as well as up-link within a wireless communication system.
