Precision Waveguide Radiation for Satellite Communications
Probe waveguide antennas play a critical role in SatCom RF testing and validation by efficiently converting guided RF energy within a waveguide into free-space radiation, and by receiving radiated satellite signals back into waveguide transmission paths. This capability is essential for accurate characterization of satellite payload components, ground station hardware, and RF front-end subsystems.
In Q-Band and V-Band SatCom systems, maintaining signal integrity is especially challenging due to higher free-space loss, atmospheric absorption, and component sensitivity. Waveguide probe antennas minimize these issues by providing low-loss signal coupling, high power handling, and stable radiation patterns across wide bandwidths.
