High-Gain Antennas

Reflectarray Antenna

Description

The reflectarray technology paves the way for advanced communication systems, extending beyond solar missions to encompass high-data rate telecommunications on small satellites. It facilitates the development of advanced downlinks and inter-satellite connections, with a particular focus on enabling long-distance communications between Earth and small satellite platforms.

This innovative technology effectively emulates the performance of a parabolic reflector but utilizes flat panels instead. These panels are folded over each other and then folded again onto a carrier when not in use, allowing for compact storage and easy deployment. This compact and deployable design is well-suited for the space-constrained environments of small satellites.

The flat panels of the reflectarray antenna possess reflective properties for radio frequency (RF) waves and enable local control of the phase of the reflected waves. Additionally, the antenna incorporates a robust structure to ensure stability and rigidity.

Furthermore, mechanisms such as folding and/or panel guiding mechanisms, positioning and/or locking devices between the lateral and central sections, and passive thermal control are implemented to enhance the antenna's functionality.

The reflectarray operates across a frequency range spanning from X to Ka bands. Notably, the Ka-band frequency is particularly suitable for long-distance communications, making it ideal for missions to distant destinations such as Mars exploration.

Please note that our reflectarrays are not a COTS (Commercial Off The Shelf) product. They are custom-made upond demand, hence why we do not have a generic datasheet to provide.
