PhD offer: Compact Antennas with Radiation Constraints Manufactured using Additive Technologies for UAV and Nanosatellites Applications


The interest in small-size autonomous platforms is growing rapidly. UAVs are for instance more and more used in the domains of media, agriculture and industry. Another example concerns the space industry where nanosatellites could yield a significant reduction in the launching and operation costs. These two domains share the common constraint of embedding complex systems on autonomous small-size platforms. This integration constraint is notably important for one of the key-elements of the system, i.e. the telecommunication antennas. These antennas have to be compact and of small weight in order to optimize the UAV airworthiness or the nanosatellite performances. Besides, they radiation pattern must be controlled.


The main objective of this PhD thesis, available at two University labs. (ENAC and ISAE-Supaéro) is to design antennas integrated on small-size platforms, i.e. UAVs and nanosatellites, with strong constraints both in terms of size and radiation performances (radiation pattern and polarization). To do so, we will analyze the capabilities of 3D printed structures to obtain dielectric resonator antennas. The 3D printing will be used to locally control the material index of refraction. The design of such antennas is an innovation which may offer new degrees of freedom to optimize RF properties.
