Metasurface-inspired antenna in cavity for GNSS applications

The objective of this work is the development of a miniature antenna integrated inside a rectangular metal cavity. This antenna must cover three of the GNSS systems at the same time (Galileo E1, GLONASS G1 and GPS L1). To this end, the bandwidth must be larger than 60 MHz. A model based on metasurfaces will be presented, as well as the results obtained in simulation. Prototypes are currently being manufactured and measurement results will be presented during the oral communication.
