About
The High Gain X-Band Antenna delivers a realized gain exceeding 20 dBi at 8.2 GHz, achieved through a large 200 × 200 mm aperture that concentrates RF energy into a narrow 9° pencil beam. This level of gain translates directly into a significantly improved link budget and higher achievable data rates, making it ideal for Earth observation or remote sensing missions with demanding payload downlink requirements. The antenna’s Half Power Beam Width of approximately 9° produces a highly directive pencil beam that maximises radiated power towards the ground station during the downlink window. The axial ratio stays below 1 dB within ±5° of boresight, ensuring excellent circular polarization purity and minimising losses due to Faraday rotation. Featuring only a 200 × 200 mm aperture, the High Gain X-Band Antenna maintains a total height of only 16 mm, with less than 8 mm of protrusion above the satellite panel. Protected by a PEEK radome with SG121FD white paint on flight models, it withstands thermal extremes from −120°C to +120°C and prevents electrostatic discharge events. The antenna operates from 7.9 to 8.5 GHz (600 MHz bandwidth) in LHCP or RHCP, with a reflection coefficient better than −18 dB and an axial ratio below 1 dB at ±5°. It is compatible with the Anywaves Test Hat for X-Band Antennas and is ITAR Free.
