Reflector Antennas


Antennas represent one of the company´s four 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 focus at HPS: the company´s specialization 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.
