Oliver Leisten, the Chief Technology Officer at Helix, delivers a keynote speech at MMA (Microwave Materials and Applications) 2023
Helix Geospace’s Chief Technology Officer, Oliver Leisten, has received an exclusive invitation to present at the MMA (Microwave Materials and Applications) 2023 conference. During his session, he will delve into the intricate realm of radiation physics on GNSS helical antenna, shedding light on the critical role of electrical isolation in autonomous radiation. Oliver will highlight how this innovation offers substantial benefits to modern wireless devices and resilient GNSS positioning systems, revolutionising the way we approach wireless communications.
In tandem with his presentation, the skilled technical team at Helix Geospace has meticulously prepared a comprehensive whitepaper. This document delves deep into the subject matter, providing a detailed exploration of “The Use of Dielectric Materials to Enable Electrically Small Antennas with better efficiency.” Furthermore, it introduces Helix Geospace’s pioneering dielectric-based approach, a cutting-edge solution for achieving top-tier performance in electrically small antennas.

Helix focuses on high performance antenna technology for satellite communications and resilient PNT (Position, Navigation and Timing). With variants for GPS, Galileo GNSS constellations and the Iridium LEO satcomms constellation, Helix antennas are multifrequency resonant devices with tightly targeted frequency discrimination. They utilise multiple helical conductor filaments on a high dielectric constant ceramic core. The selective nature of the design assures integrity of data delivered to the receiver enabling positional accuracy to 10cm to be computed, and high levels of resilience against environmental and deliberate disruption. The helical antenna resonance means that troublesome reflected signals, typical of modern cities’ ‘urban canyons’ are ignored, while the on-frequency accuracy makes the system resilient to ‘noisy neighbour’ spectrum interference and deliberate jamming. All this comes in a compact and robust form factor light enough for drones and small enough for vehicle aesthetics. Using this best-in-class antenna technology enables the CRPx anti-jamming/spoofing systems deliver the optimum defence against malicious attempts to undermine satellite navigation and communications with the best SWaP-C.
