Multi-permittivity 3D-printed Ceramic Dual-Band Circularly Polarized Dielectric Resonator Antenna for Space Applications – Measurement

This document follows a previous article which present the design of a Dielectric Resonator Antenna (DRA) developed by ANYWAVES with the support of the French Space Agency (CNES) and the help of an academic partner XLIM. This antenna is circularly-polarized, dual-band (Upper-L-Band (1.559 – 1.61 GHz) and TT&C S-Band (2.025 – 2.29 GHz)) and designed to be integrated on a CubeSat or Nanosatellite. The particularity of this DRA is that the dielectric part is a structured 3D-printed block of Zirconia with two different permittivities. Two different feeding lines have been designed: with and without an integrated diplexer. Two breadboards of this antenna had been fabricated and measured in the premises of XLIM.
