Rectangular Standard Waveguide Probes

ASY-RWG Series

Open Ended Rectangular Waveguides Probes

Product Description

Open-ended Rectangular Waveguide Probes (RWG) are commonly used as near-field probes in planar near-field and cylindrical near-field antenna measurements. The probe design is based upon standard rectangular waveguides and consequently the probes can be manufactured for any standard frequency band from 500MHz up to 60GHz. The radiation characteristics of RWG can be well predicted by analytical formulas that facilitate a simplified probe pattern correction.

ASYSOL RWGs are equipped with an integrated coaxial connector, absorber shield, and dedicated mechanical interface with a standardised mounting flange.

All RWGs are supplied with a test report, including measurement results of the main characteristics:

Reflection coefficient
Sweep gain
Sweep on-axis cross-polarisation
Pattern at a series of frequencies across the band
