Direct Radiating Array Antenna
Anywaves
The Anywaves Direct Radiating Array Antenna is a custom-designed, high-gain flat antenna solution for satellite payload applications in Ku and Ka band, where high power handling and a low profile are the primary constraints.

- Polarization
- Left or Right Hand Circular Polarization (custom)
- Realized gain
- > 30 dBi (design target — scalable per mission)
- Fractional bandwidth
- ~10%
- Profile thickness
- < 15 mm (without connector)
- Sidelobe levels
- ~15 dB
About
With a scalable patch array architecture delivering gains above 30 dBi within a 10% fractional bandwidth, it addresses the Ka-band link budget requirements for payload telemetry downlinks and inter-satellite link communications. The antenna maintains first sidelobe levels of approximately 15 dB, ensuring clean beam quality alongside high gain. Its total profile thickness is less than 15 mm without the connector. Available in LHCP or RHCP, and protected by a space-qualified white paint radome for ESD protection and thermal stability. All parameters — frequency, gain, footprint, beam characteristics — are defined jointly with the customer and tailored to each mission. Qualification campaign included (mechanical vibration, thermal vacuum cycling, power-handling testing). ITAR Free.
