A 220-300 GHz Offset Dual-Reflector Antenna for Point-to-Point Radio

This paper presents a feasibility study of a classical offset dual-reflector configuration for sub-THz high gain wideband antenna demanded for radio links with multi-Gbps throughput. To the best of the authors’ knowledge, this is the first demonstration of the designed, fabricated and tested offset Cassegrain antenna practical at 220-300 GHz. Antenna embodiment demonstrates notable size and weight.
