XAAE X-Band Antenna Assembly

The XAAE is a part of the Egyptsat X-band antenna assembly, which consists of two redundant on-board 2-axis antenna pointing mechanisms (APM).

Key technical challenges:

  • Dimension: overall length of antenna < 700 mm (minimization in terms of mass and envelope)
  • Cross polarization isolation > 30 dB within the effective beam width of +/- 4.25 deg.
  • Antenna gain to be > 25 dBi

Key functionalities:

  • X-band Tx 8.025 – 8.400 GHz on-board antenna
  • Dual circular polarized

Project partner:
Airbus Defence & Space GmbH
