CHARACTERISTICS OF OVERSIZE CIRCULAR WAVEGUIDES AND TRANSITIONS AT 3-MILLIMETER WAVELENGTHS.
Abstract
The physical and electrical characteristics of a 0.995 in. diameter oversize circular waveguide and its associated transitions operating in the 92- to 96-GHz band are described. Both linear and nonlinear taper transitions were employed in converting from the WR-10 dominant mode rectangular waveguide (0.100 X 0.050 in. ID) to a 0.995 in. diameter circular waveguide. The results of the present investigations indicate that the nonlinear taper transitions yield considerably less multimoding effects. In the 92- to 96-GHz band, the measured attenuation for a 0.995 in. diameter oversize copper circular waveguide is 0.028 dB/ft as compared to a theoretical value of 0.02 dB/ft. (Author)
