Reflector Antennas

Top Deck Antennas – Side Deployable Antennas – Dual Gridded Antennas – Large Deployable Antennas – Ka-SAR Radar Antenna System – GNSS Antennas – Ground Portable Antennas

Antennas represent one of the company´s most important subsystem domains that HPS fully covers with a portfolio ranging from side-deployable antannas, top deck- and feeder link-antennas over dual gridded, GNSS- and large deployable antennas, up to radar- and even ground-antennas.
In particular for solid refector antennas, the company specializes on Ka- and Q/V-band. Notable features of HPS antenna subsystems are their low weight, high reflectivity, low thermoelastic distortion and high eigenfrenquency.
HPS delivers antenna subsystems complete and fast – advantages which in combination with those proven quality features mentioned above have led to HPS flight heritage on board of the „Heinrich Hertz“-mission of the German space agency DLR as well as for the ESA-mission EUCLID.
