TTP’s low-cost electronically steerable antenna for Satcom user terminals

Soon-to-be-launched LEO satellite mega-constellations are set to transform global communication. TTP's antenna technology can make high-speed broadband and IoT connectivity services delivered by LEO satellites accessible via low cost user terminals.

Context

Satellite communication is poised to be transformed by services delivered by Low Earth Orbit (LEO) mega-constellations, which promise to deliver truly global high-speed broadband and IoT connectivity.

Solution

To accelerate the adoption of these services by commercial users as well as consumers, TTP is developing an electronically steerable antenna that meets the requirements of LEO satellite constellations.

Result

By making satcom terminals more affordable, TTP’s antenna technology (patent pending) can open new business streams for satellite network operators and terminal manufacturers.

U

Unlike geostationary (GEO) satellites, LEO satellites need to be constantly tracked across the sky by the user terminal’s antenna. To be able to tap latent demand in unconnected parts of the world this functionality must be achieved at low cost.

Electronically steerable antennas lend themselves to this application. But so far, none of the proposed technologies have achieved cost and performance levels that could catalyse the transformation of the global communications landscape promised by LEO satellite constellations. 

Drawing on the multidisciplinary expertise of our scientists and engineers, we have invented a differentiated antenna solution based on smart materials, which is more competitive than, for instance, traditional phased arrays based on semiconductor beamformers – both in terms of cost and performance. In addition, our electronically steerable antenna is compatible with existing satcom front-ends (BUCs and LNBs).

Our technology is suitable for Ku- and Ka-band satellite communications and, potentially, cellular 5G. The solution is highly scalable to accommodate a wide range of antenna gain levels. With this antenna, we are well placed to develop integrated low-cost satcom user terminals.

Our antenna technology will make VSAT satcom terminals more affordable and open untapped markets for the satcom sector. The technology is available for licensing and designing into our clients’ satcom solutions.
