Mitsubishi Electric Develops 28GHz Massive-element Antenna and RF Module for 5G Base Stations

Compact module achieves wide bandwidth and wide-angle beam forming

PDF Version

TOKYO, April 18, 2017 - Mitsubishi Electric Corporation (TOKYO: 6503) has developed a compact massive-element antenna and RF module that achieves a wide 800MHz bandwidth and wide-angle beamforming for 28GHz communications in fifth-generation (5G) radio base stations. Going forward, Mitsubishi Electric will confirm the module's performance for high-speed, large-capacity communication, aiming at early commercialization. The status of development will be presented at the Brooklyn 5G Summit* to be held in New York City from April 19 to 21.

-Highly efficient integration of RF device realizes compact size

Development Background

To accommodate the rapid increase in mobile traffic, and realize advanced services and applications, 5G technologies are being developed worldwide with the expectation of commercialization as early as 2020. 5G will deliver ultra-high-speed transmission of 20Gbps, far exceeding the 3Gbps rate specified for 4G. Two key technologies are Massive Multiple-Input Multiple-Output (MIMO), which use high frequency bands to secure wide bandwidth, and MIMO, which spatially multiplexes multiple signals at the same time in the same frequency while compensating for large propagation loss in higher frequencies through the use of multi-element antennas. Mitsubishi Electric's new antenna and RF module for 5G base stations will be used for Massive MIMO. This work includes a part of the results of "The research and development project for realization of the fifth generation mobile communications system" commissioned by Japan's Ministry of Internal Affairs and Communications.
