3D Printed All-GNSS Bands Miniaturized Antenna and Array for Robust Satellite Navigation

Satellite navigation is a fundamental asset in today’s mobile platforms to determine position, velocity and time. Such capability must be protected from unintentional or intentional interferences, in order to ensure availability of correct navigation information at all times. The best performing countermeasure to that threat is the use of multi-antenna systems, able to mitigate interferences by placing nulls in the direction of the interferer. The present work shows the design of a 3D printed miniaturized multi-antenna array, able to operate at all GNSS bands and still fitting into a 100 mm diameter footprint, hence suitable for mobile applications, such as UAVs.
