Smart Antennas and Front-End Modules in Q-band for Backhaul Networks

Abstract

[EN] As mobile operators face increasing density of base stations as well as growing bandwidth requirements, mobile backhaul has become the new challenge. This article defines the architecture for future mobile backhaul networks as proposed in the framework of the FP7 EU SARABAND project. This solution exploits a new and wider frequency spectrum band, the Q-band (40.5 43.5 GHz), to provide massive amounts of capacity. However, for the full deployment of such backhaul networks, new technology development in the Q-band must be addressed. In particular, this article gives an overview of the disruptive technology on antennas and front-end modules developed within this project.
