Antenna solutions utilising patented technology

We have developed and patent-protected a completely novel approach to creating the smallest antennas capable of delivering world-beating performance for GNSS and terrestrial or satellite data communications. It combines material science, RF innovation, and Industry 4.0 precision manufacturing, and we call it DielectriX.


who. what. where.

Helix Technologies was founded in 2017 by Oliver Leisten to commercialise his extensive work in the field of dielectric-loaded multi-filar antennas. By 2019 the leadership team had expanded to include engineers and entrepreneurs who are driven to deliver optimal antenna performance to the autonomous, aerospace, critical national infrastructure and the defense and security sectors.

Our Dielectrix™ technology is the core of our multi-helical antenna-based solutions for resilient precision PNT. Advanced material science drives our antenna performance and we have pioneered and patent protected the use of specialised high dielectric constant materials.

Helix Geospace’s headquarters is based on the Harwell Campus, Oxfordshire in the United Kingdom, which is central to the UK’s ‘space cluster’.


design. prototype. test.

Helix’s design methodology is optimised for rapid development of new antenna products, both as standard commercial off-the-shelf solutions and customised antenna solutions for specific customer applications. We have created a unique ‘Industry 4.0’ manufacturing process capable of meeting the micron-accurate fabrication precision that delivers the performance benefits of DielectriX.
