Description

Anteral’s X-Band SAT Feeding Network uses an innovative circumplexer design to feed antennas operating with right-hand circular polarization (RHCP) in the transmit channel and left-hand circular polarization (LHCP) in the receive channel. This compact passive device integrates a polarizer and a diplexer into a single component, reducing mass, size, and potential points of failure.

The circumplexer design also improves passive intermodulation (PIM) performance by minimizing the number of flanges and screws. The system delivers high isolation greater than 65 dB, a return loss of 20 dB, and an axial ratio below 1 dB, ensuring reliable operation across the X-Band.

Built for space-constrained missions, this feeding network is ideal for smallsats and satellite systems that require precision performance with reduced footprint.
