Combining the advantages of reflector antennas and printed antenna arrays, reflectarrays achieve high gains while being low-profile without the requirement of a complex feeding network.
Unlike conventional reflectarrays which are made of elements printed on a dielectric substrate and have a metallic ground plane, the solution proposed for this internship is to remove all metallic parts and replace them with a structure entirely made of dielectric using 3D printing technology.
We aim to replace the metallic reflector plane by a dielectric mirror based on a bandgap structure.
The schedule of this internship is detailed below:
- Design and study of a dielectric mirror based on bandgap structures using electromagnetic simulations.
- Design and simulation of the reflectarray
- Realization of the prototype in 3D printing. Radiation pattern measurements in the anechoic chamber of the laboratory.
The design frequency range is the W-band and more specifically 76 to 81 GHz for radar applications purpose.
- Skills in electromagnetism and antennas
- Knowledge of large antennas and antenna arrays would be appreciated.
- Experience with electromagnetic simulation software (CST, HFSS)
