A High-Throughput Deployable Antenna based on Not-Aligned Reflectarray Panels

Abstract

This contribution describes a deployable large multi-faceted reflectarray to be embarked in different aerospace vehicles. The structure comprises several low-profile panels that are assembled to follow an equivalent parabolic reflector. An example of this antenna concept is designed to operate in Ka-band and dual-linear polarization. It provides high-gain, low-losses, and a bandwidth significantly higher than the one achieved with a conventional deployable reflectarray. Therefore, the proposed antenna exhibits high-throughput performance with integrability with the vehicle platform. Such features are of particular interest for space missions and some terrestrial communications.
