Image of Anywaves - TT&C Ka-band Antenna on the satsearch marketplace

Key highlights

Highly reliable, compact Ka-band antenna for telemetry, tracking, and command (TT&C) in demanding space applications.
Available in two models:

Tx (transmission)
Rx (reception)

Scalable in frequency to meet varying operational needs.
Choke ring design to minimize multipath and interference.
Single or dual circular polarization (RHCP/LHCP).
Hemispherical gain pattern with excellent axial ratio stability.
Reflection coefficient better than –18 dB for high efficiency.
Engineered for harsh space conditions, lightweight, ITAR-free.
Suitable for commercial and scientific missions.

Applications

Designed for telemetry, tracking, and command (TT&C) operations in demanding space missions, the Choke‑Ring Ka‑Band Antenna excels where signal integrity and precision are paramount.

Its choke‑ring architecture suppresses multipath and interference, enhancing link reliability even in challenging environments (e.g., deep space, cluttered orbital regimes).

Available in dedicated Tx and Rx versions with single or dual RHCP/LHCP polarization, it delivers stable hemispherical coverage across respective Ka‑band frequencies, while maintaining a low reflection coefficient (< –18 dB) for high efficiency anywaves.com.

Its compact, lightweight, ITAR‑free design simplifies integration into both commercial and scientific platforms, underpinned by rigorous acceptance testing—all backed by comprehensive engineering support and documentation.
