Adaptive downtilt for cellular base stations

Efficiency, reconfigurability, and power consumption are paramount for future communication systems in applications such as cellular handsets, base stations and home networking systems. We present our work in the European PANAMA project which addresses the associated challenges. Our work focuses on the improvement of the efficiency and reconfigurability of base transceiver stations (BTS). Starting from the requirement for adaptive downtilt in these systems, we present a novel scalable, wideband, fully electronic downtilt system that can be realised on a single printed circuit board (PCB).
