Massive MIMO Ultra-Wideband Communications Using Multi-Mode Antennas

The demand for ultra-high data rates is an ongoing challenge in wireless communications. Towards that goal, massive MIMO is currently considered as a key technology for the development of 5G systems. Hence, baseband processing and advanced antenna design need to be considered simultaneously. In this paper, we provide a massive MIMO system proposal based on multi-mode antennas. The system is crafted for operating as an UWB system in the 6-8.5 GHz frequency band. This contribution includes design considerations for UWB systems, a comprehensive overview of multi-mode antennas, and highlights the potential of employing multi-mode antennas in massive MIMO systems.
