Innovative BANT-1 reflector antenna from HPS for Reflex: exemplary symbiosis of NewSpace and established space-SME

NewSpace – this means, among other things, speed in development, production and provision, paired with innovative versatility as a leitmotif for the performance of the product. A current example of this is the broadband reflector antenna developed for the new Reflex Aerospace satellite by space SME HPS GmbH (Munich, Germany) with a broadband spiral as an axial feed. The primary development goal was to achieve a large bandwidth and considerable gain while at the same time limiting the time from order to delivery to the customer to just 12 months. The antenna consists of a prime focus reflector with a diameter of 700 mm and an f/D ratio of 0.32, which is fed by a compact ultra-wideband cavity-backed spiral (CBS).

HPS thus succeeded in meeting all customer expectations in terms of performance, price, and timing while adhering to best practices and strict quality management; the project can serve as a striking example of an exemplary symbiosis between NewSpace and established space SMEs towards “NextSpace”.

The Reflex satellite will be launched on board a Falcon9 as part of a SpaceX rideshare 12 mission.
