Description

Anteral’s K/Ka-Band Feeding Network is a compact dual-circular polarization system designed for satellite antennas operating across K and Ka bands. The unit includes two ports for RHCP and LHCP transmission and two ports for RHCP and LHCP reception, forming a fully reconfigurable subsystem.

At the core of the system is a high-isolation diplexer and a high-performance orthomode transducer. Together, they provide over 80 dB of isolation between TX and RX channels. The integrated polarizer ensures accurate polarization control, maintaining a typical axial ratio below 1 dB.

Built for compact integration, the unit supports WR-42 and WR-28 interfaces and offers low return loss at 18 dB. It’s ideal for advanced satellite systems where performance, flexibility, and efficient signal separation are key.
