About
The Compact X-Band Antenna packs a realized gain of 15.5 dBi at 8.2 GHz into an envelope of just 100 × 100 × 16.2 mm with a protruding height of only 6.5 mm above the satellite panel. This ultra-low profile makes it the ideal choice for platforms with tight surface constraints, while its directive broadside beam maximises the data-rate transferred during each ground station pass. The antenna is protected by a PEEK radome coated with SG121FD white paint on flight models, providing thermal protection of internal parts, as well as electrostatic discharges. The radome maintains consistent RF performance — including the exceptional axial ratio of less than 1 dB for elevation angles from 0° to ±5° — throughout the full mission lifetime. Featuring a footprint of 100 × 100 mm and a mass of 70 g, the Compact X-Band Antenna fits within a 1U CubeSat surface and imposes a minimal mass budget impact. With a bandwidth of 600 MHz (7.9–8.5 GHz) and a radiation efficiency above 70%, it delivers high-quality payload telemetry downlink performance on board of any LEO satellite platform, ranging from 1U CubeSats to larger small satellites. Designed for nanosatellites and LEO platforms, the Compact X-Band Antenna features a directive narrow beam (~20° HPBW) that concentrates all RF energy towards the ground station during the pass, maximising data throughput. Its PEEK radome ensures protection against thermal and radiation environments. Compatible with the Anywaves Test Hat for X-Band Antennas, it is supplied with full acceptance testing on flight models.
