Internship | Foldable Reflectarray for small cubesat applications

About this position

How can high-gain antennas be designed for small Cubesat systems?

What will be your role?

Reflectarrays are an attractive solution for high gain antenna system in space (Earth observation, SATCOM, etc.). High gain antennas usually are implemented by using quasi-optical systems realized by one or more curved reflectors (Parabola, Cassegrain, Gregorian, etc.). Such type of antenna system can be challenging to realize foldable way, in order to be mounted in a small cubesat much smaller than the size of the antenna.
Reflectarrays mimic the curved reflector with flat panels filled with multiple passive radiating elements, allowing to realize a high gain antenna systems, more suitable to be folded and integrated in a small cubesat platform.
The main goal of this project is to study a foldable reflectarray solution in terms of radiating element and quasi-optical system, in order to minimize the losses and therefor...
