Precision gold plated near field waveguide probes with frequency coverage from 75 GHz to 1.1 THz. Specifically fabricated for THz applications in near field antenna scanning, these rugged waveguide probes are available in custom or standard lengths. The chosen length is a compromise between loss and distance to the field to be sampled . Tapered to reduce free space reflections and fitted with IEEE 1785.2 flanges above 300 GHz for lowest connection loss and minimal reflection. Ideal for electric field sampling of antennas, these probes have a quasi-omnidirectional uniform beam pattern, see inset.

1. New waveguide definitions are in use above 110 GHz, as defined by IEEE standards up to 1.1 THz.
2. All units are machined from solid brass and gold plated.
3. There are variations in industry 'standard' flanges. Above 300 GHz additional dowel pins per IEEE 1785.2 are fitted unless otherwise requested.
4. Waveguide WR03 historically covers 220-325 GHz, whereas the new standard WM-864 extends coverage to 220 – 330 GHz
5. Standard waveguides are 25 mm long and machined in solid brass gold plated. Custom lengths and materials are available to order.
6. How to make a request: specify Model number with required length eg. THZWGP-03-50 is a probe of length 50 mm. Email to: sales@vivatechthz.com
