K/Ka-Band SAT System

Description

Anteral’s K/Ka-Band SAT System is a compact, four-port solution designed for smallsats and advanced satellite platforms. It operates in both transmit (17.3–21.2 GHz) and receive (27–31 GHz) bands, offering dual-circular polarization with less than 1 dB of axial ratio—thanks to an advanced polarizer design developed in-house.

With 80–100 dB of isolation between TX and RX channels, this system ensures clear, interference-free performance for demanding RF environments. The antenna delivers 21 dBi of directivity in a lightweight 2U form factor, making it ideal for NewSpace applications where mass and volume are limited.

Multiple clamping points allow for mechanical customization. The system is currently qualified for a 2024 flight program and supports both RHCP and LHCP on TX and RX ports.
