3D Printed Ceramic Low-Profile GNSS Antenna for SmallSats

This paper presents the design of a compact GNSS (Global Navigation Satellite System) L1 band patch antenna. This design features a 3D printed structured substrate, with customizable permittivity, enabling a compromise to be reached between miniaturization and RF performances. Mechanical and thermal tests show the ability of such design to withstand the harsh environment constraints of SmallSats. A low-profile variant is also presented for Nanosatellites applications.
