Standard Waveguide Probes are directional coupling or radiation devices used in microwave frequency bands, enabling efficient signal transmission through precisely engineered waveguide-to-coaxial transition structures. The core components consist of a waveguide interface (e.g., WR-90 / X-band), a coaxial connector (typically SMA or N-type), and an impedance-matching probe. Operating across a frequency range of 2.6–110 GHz (depending on the WR standard), these probes offer low insertion loss (<0.5 dB), high return loss (>15 dB), and high power handling capacity (with peak power reaching kilowatt levels). Widely employed in applications such as anechoic chamber calibration, antenna near-field testing, waveguide system fault diagnosis, and terahertz measurement systems, they serve as critical transitional components connecting waveguide and coaxial systems.
