Project Sunride | Avionics Engineer
First flight computer in the MRAS Line for Project Sunride - in collaboration with Spacefleet company,
First version of Sunride Groundstation - designed to interface with DART & future MRAS designs,
Second iteration of MRAS - improved from DART, with a focus on SMD and RF capabilities,
First attempt at an active QFH antenna, optimised for GNSS satellites - uses SAW filtering & LNAs
Third iteration of MRAS - pure flight-logger computer, focus on compact size, deployment channels, bare metal SMD, and BT.
First development of an MRAS Rocket Tracker - GPS Tracker using 2.4GHz LORA & ublox MaxM10Q GPS.
Was used on Karman Bravo & Desert Winds to an altitude of ~8.2km.

Sheffield Undergraduate Research Experience (SURE) | Carbon Fibre Antennas
Background
I came up with the idea as a result of my involvement in model rocketry, where we faced an issue with the rocket's carbon fibre body tube severely attenuating RF signals due to its high conductivity. The decision to use Carbon Fibre was made without consulting the avionics team, which was a lesson in good team communication.
Jokingly suggesting that the entire rocket could be an antenna sparked a genuine curiosity about using Carbon Fibre for antennas. I approached an academic specializing in meta-material antennas, and though I failed to get a working prototype in the six week scheme, the experience revealed fascinating properties of Carbon Fibre. This motivated me to continue exploring Carbon Fibre in RF applications for my individual 3rd-year project.
Personal analysis for CF material as a conductor + finding a solution to increase measured conductivity
Countless models & custom material profiles to accurately simulate CF antenna prototypes
Building copper and CF prototypes and measuring S-parametres to prove epoxy-cured CF antennas as a proof of concept
Main Discoveries - there is very little public literature revealing this information.
• Pure CF had potential applications in wearables, and RF surfaces technology - due to its unique an-isotropicity, and weave form.
• Pure CF cured with epoxy was too lossy, and resistive to enable a functional antenna prototype with the tested topologies.
• Treated CF (infused with metallic coating/mesh) is proven to be viable as an antenna material by literature.
• Up to 5 layers of stacked CF increased conductivity by 3x.
EEE381 Third Year Research Project | Flexible Artifical Magnetic Surfaces (AMS) with Carbon Fibre
Public Engagement Video || Symposium || Final Report
Building on my SURE Scheme, my supervisor and I discussed using carbon fiber to create a flexible Artificial Magnetic Surface (AMS). After reading up on it, I decided to give it a try.
The idea was to developing a carbon fiber weave with a polyester dielectric, targeting 2.4 GHz for wearable healthcare applications (e.g. wireless diabetes monitors). This AMS could serve as an efficient ground plane for wearable antennas, preventing detuning without the need for precise distance adjustments. An added benefit over metal was its ability to reduce SAR exposure to human tissue, thanks to superior filtering and reflective properties than a typical conductor.
The results and full investigations are in the relevant links above, however here are some relevant pictures that help capture the project.
