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