Data Downlink Antennas

Very High Gain (>20dbi)
X-Band Payload Telemetry Antenna

Description

Introducing Anywaves’ High-Gain X-Band Antenna, specifically engineered to meet demanding satellite payload communication requirements. This advanced antenna is ideally suited for missions requiring high data-rate telemetry, ensuring robust and efficient data transmission.

Featuring a gain exceeding 20 dBi at boresight, our X-Band antenna provides exceptional performance across the 7.9 GHz to 8.5 GHz frequency range . Its well-engineered circular polarization (available in both right- and left-hand versions) delivers optimal polarization purity, maintaining axial ratios under 1 dB within ±7.5° off boresight at 8.2 GHz, thus reducing the risk of polarization mismatch due to Faraday’s rotation for more reliable and robust long-range transmission link.

Designed for harsh space environments, the antenna incorporates a protective PEEK-coated radome finished with durable SG121FD white paint suitable for extreme temperatures (-120°C to +120°C).

Compact and lightweight (200 x 200 x 16 mm³), the antenna features 4x M3 unthreaded mounting holes and coaxial SMA female connectors (50 Ω).

Rigorously tested for RF, mechanical, and thermal reliability, this antenna represents a reliable and versatile solution for international satellite operators seeking to maximize payload efficiency and communication capabilities.

NB : this antenna is compatible with Anywaves Test Hat for X-Bands Antennas
