Design and analysis of superstrateintegrated differentially-fed circularly-polarised antennas are presented. The antenna consists of a metallic patch fabricated multilayer space-qualified printed circuit boards, integrated by a dielectric superstrate on top to establish suitable resonant condition for high-gain operation. The driven patch is excited by two orthogonal differential feeding pairs using sequential rotation technique for pattern symme...

This work investigates the characteristics of the antenna of this type on composite PCB in terms of manufacturing techniques and tolerances, mechanical and thermal performance. The objective is to validate that the designs are capable of offering stable radiating characteristics, whilst providing high structural strength with low mass. The results are compared with the ones on conventional builds, and have demonstrated attractive properties that ...

Working on the Gaia space observation Satellite since 1993, the European Space Agency has a mission to compile a 3D catalogue of approximately 1 billion astronomical objects in the Milky Way. Printech Circuit Laboratories and E2V have collaborated for over 10 years, resulting in the most powerful camera ever to be launched into Space on the Gaia satellite.
