WR18 Combined Input Waveguide Open Probe

WR18 Combined Input Waveguide Open Probe

This product is a professional grade Antenna Near Field Measurement Probe with a combined waveguide and coaxial input design. The model is built around a WR18 (BJ500) waveguide size and comes with a precision 1.85-K connector. It is constructed from copper and aluminum materials for durability and reliable electrical contact. As a Waveguide Open Probe, this unit features a simple yet effective open ended structure. The combined input design gives users flexible feeding options. Unlike rigid single purpose probes, this unit can work with different test equipment setups. The open waveguide structure delivers pure polarization and good compatibility with standard waveguide interfaces. This makes the probe a solid choice for engineers who need accurate field characterization in the millimeter wave range.

This Near Field Probe operates in the millimeter wave band from 40GHz to 60GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 2.5, which is typical for this type of open structure probe. The gain is a solid 8dB, providing enough signal pickup for most near field scanning tasks. The 1.85-K connector is a precision type made specifically for millimeter wave work. The probe offers high spatial resolution, which means users can capture fine details of the electromagnetic field. The beam profile measurement is accurate and reliable. The probe also handles high power levels well and resists outside interference. One of the key benefits is field distribution visualization. Engineers can see how the field behaves across the scanned area, which helps locate defects in antennas or systems in a very direct way.

One clear strength of this Waveguide Open Probe is its performance in antenna near field scanning and field mapping applications. The pure polarization characteristic ensures that measurements are not contaminated by unwanted cross polarization signals. This is critical when characterizing high performance antennas. The probe is widely used for microwave antenna amplitude phase scanning and field distribution mapping. Its main application areas include low frequency EMC interference troubleshooting, antenna near field and far field measurements, leakage positioning, and radar satellite specific tasks. For engineers working on phased Array Antenna testing, reflector diagnosis, or satellite communication system validation, this unit provides a stable and repeatable measurement reference. The robust build also means the probe can handle regular use in busy lab environments without issues.

In practical use, this Antenna Near Field Measurement Probe handles professional millimeter wave diagnostic tasks very well. For antenna test ranges, it serves as a reliable receiving probe for near field scanning systems. Its 8dB gain and stable performance help produce clean field maps that reveal amplitude and phase variations across the antenna aperture. In EMC work, it helps locate interference sources and identify leakage points in shielded enclosures or on equipment surfaces. The copper and aluminum construction gives the probe good strength while keeping it light enough for mounting on automated scanner arms. The combined input setup allows quick connection to different test equipment, which is a real help when moving between different measurement systems. It stands as a solid example of how a well designed Waveguide Open Probe can meet the demanding needs of modern millimeter wave near field measurement and antenna diagnostics.
