7.6to26.5GHz High Isolation Near Field Probe

Coaxial Input Dual Linear Polarization Probe with I Shape Stand

This product is a high performance Antenna Near Field Measurement Probe with a coaxial input structure and dual linear polarization capability. The probe comes with a precision 2.92 K type connector and operates from 17.6GHz to 26.5GHz. It is built from copper and aluminum materials for good durability and consistent electrical performance. As a Coaxial Input Probe, this unit is fed through a coaxial cable, making it easy to connect to standard RF test equipment. As a Dual Linear Polarization Probe, it can receive both horizontal and vertical polarizations independently. The port isolation is rated very high, which means there is minimal signal leakage between the two polarization channels. This allows engineers to measure co polarization and cross polarization responses accurately in a single scan.

This Near Field Probe operates in the frequency range from 17.6GHz to 26.5GHz, covering the K band. The Voltage Standing Wave Ratio (VSWR) is rated at 1.8, which is good for a dual polarized probe. The gain is a solid 10dB, providing strong signal pickup for near field scanning tasks. The 2.92 K connector is a precision type made for high frequency work. The probe includes an I shape stand with absorbing material coating. The stand provides stable positioning during measurements, while the absorbing material helps reduce unwanted reflections from the mounting structure. The probe offers high spatial resolution, allowing users to capture fine details of the electromagnetic field. The beam profile measurement is accurate and reliable. The probe handles high power levels well and resists outside interference effectively.

One clear strength of this Dual Linear Polarization Probe is its high port isolation. With isolation rated very high, users can measure one polarization while the other port picks up almost no signal. This is critical for characterizing modern antennas that use polarization diversity, such as those in satellite communication and advanced radar systems. The pure polarization characteristic ensures that measurements are not contaminated by unwanted cross polarization signals. 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.

In practical use, this Coaxial Input Probe handles professional diagnostic tasks very well. For antenna test ranges, it serves as a reliable receiving probe for near field scanning systems that require polarization data. Its 10dB gain and high isolation help produce clean field maps that reveal both co polar and cross polar field behavior. The I shape stand allows users to position the probe accurately and leave it in place while taking measurements. This frees up both hands for operating the test equipment. The copper and aluminum construction gives the probe good strength while keeping it light enough for easy handling. The 2.92 K connector is robust and suitable for repeated connects and disconnects. It stands as a solid example of how a well designed Dual Linear Polarization Probe with a proper stand can meet the demanding needs of K band near field measurement and antenna diagnostics.
