ntered Waveguide Flange for Mi illimeter-Wave Applications

Existing waveguide flanges limitation on measurement precision above ~10 centered waveguide flange was proposed in electrical performance characterized in the W paper explores an improved ring-centered w which is backward compatible with the origin and with all its known variants, and facilitate VNA calibration using a properly aligned "thr shim. The modifications to the ring-centered are discussed and measurements in the WR-2.2 band presented. Index Terms — Millimeter-wave, standard wave, waveguides, waveguide flanges, waveguide
