Abstract
Precise measurements made in the 50 GHz to 60 GHz band on a two-mile triangular loop of 2 inch diameter helix waveguide are presented. The measuring technique is discussed in some detail regarding accuracy. A brief comparison of the experimental results with theory is made. The average measured attenuation of the waveguide varies smoothly from 2.62 dB per mile at 50 GHz to 2.32 dB per mile at 60 GHz. Fast variations versus frequency were within experimental error. Several short-radius bends of different angles were measured; losses less than 0.8 dB across the band were observed for a 42° bend made of mitered elbows.Keywords
