Sofant Technologies

Sofant Technologies is a UK company that makes antenna terminals for satellite communications. Its head office is in Edinburgh. It is registered in Scotland. The terminals are made for use on the ground, at sea and in the air.

The company uses patented RF MEMS technology. Its main product is a Ka-band antenna terminal for mobile broadband. Uses include in-flight connectivity, communications on the move and maritime communications. The terminals work across LEO, MEO and GEO satellite networks.

The company says its terminals are small, light and passively cooled, so they need no fans. They switch beams fast, and they can serve several beams and orbits at once. Sofant says they are built to work in very harsh places. The design is modular, so it can be changed fast for a customer.

Sofant also stresses cost and size. It says its terminals use little power. Its engineers worked to cut RF losses at each stage of design. The company says it designs for volume production. To do this, it uses mature consumer electronics technology and proven high-volume assembly methods. It has partnered with established suppliers in high-volume consumer markets. Its test methods are low cost and easy to scale.

Aircraft are one of the main uses. In May 2023, Sofant and Inmarsat Government announced they would work together on a phased array antenna for aircraft. In October 2025, the company showed a world-first RF MEMS beamforming result at Tech Tour Defence in Paris.

Sofant has also named a new chairman and a new satcom expert to help its growth plans. The company has pages for products, careers and news, plus a contact form and a datasheet request. A newsletter sign-up lets visitors follow company updates.
