Improved Millimeter Waveguide Flanges Improve VANA Performance

Present millimeter waveguide flanges are major limitation when making precision measurements, or when attempting to build precision devices. New waveguide flange designs for all of the MMW bands which will mate with existing flanges but offer much improved performance are presented. This includes both rectangular and double ridged waveguide. Data showing the improvement is included. Flanges on existing equipment may be upgraded for improved performance.
