Multi-functional full-duplex radios for terrestrial and non-terrestrial communication and sensing (MULTIRACS)

Research Project, 2025 – 2027

The MULTIRACS project is focused on creating an innovative and multi-functional transceiver and antenna front-ends that operate within the emerging FR3 frequency band (7-24 GHz), for which optimal technical solutions have not been completely identified yet. The transceiver and RF front-end consists of predominantly digital functionality, innovative RF circuits and high isolation filtering antennas, providing wide reconfigurability for various scenarios and usage cases. This adaptability enables scalable solutions, allows energy efficiency and sustainable resource management as the same hardware equipment can accommodate diverse applications, unlike the current scenario where separate modules of  hardware are needed. The proposed RF systems in upper midband spectrum (7-24GHz) solution includes highly adaptive 3D antenna arrays with integrated RF as well mixed signal circuitry.  which also incorporate unique filters for reducing out-of-band emissions and enabling high capacity full-duplex communication within the band of interest.
