Choke Ring TT&C Ka-band Antenna

Description

The TT&C Ka Choke Ring Antenna is a highly reliable, compact solution for telemetry, tracking, and command operations in the Ka-band, designed specifically for demanding space applications. It is available in two distinct models: one dedicated to reception (Rx) and the other to transmission (Tx). The design can be scalable in frequency to meet different operational needs.

Utilizing a choke ring design, this antenna minimizes multipath and interference effects, ensuring precise signal transmission and reception even in challenging environments. It offers single- or dual-circular polarization (RHCP/LHCP) and provides optimal performance across the 19.7–20.2 GHz (Tx) and 29.5–30 GHz (Rx) frequency bands. This antenna has a hemispherical gain pattern, coupled with excellent axial ratio stability across a wide angular range. The reflection coefficient is better than -18 dB, ensuring minimal signal loss and high efficiency.

This TT&C Ka Choke Ring Antenna combines compact design with high performance, ensuring that satellite operators can rely on stable, high-quality communications throughout their missions. Engineered to endure the extreme conditions of space, it is lightweight and ITAR-free, making it suitable for a wide range of commercial and scientific applications.
