Abstract :
Five reduced-height, waveguide traveling standards, designed to give voltage standing wave ratios between 1.02 and 1.2, have been measured at 10 GHz by national standards laboratories in the UK, USA, Australia, Japan, Italy, and Canada. The mean values obtained by the six participants range from 1.0182 to 1.0212 on the lowest step and from 1.1976 to 1.2031 on the highest step.
