Abstract
A device for providing a low VSWR match at a bend between two straight circular waveguides has an odd number of at least three circular waveguide sections of approximately equal length along their axes mitered at both of their ends, the length chosen to be an odd multiple of a quarter guide wavelength at the desired operating frequency, and the waveguide sections being mitered so that the device is symmetrical about the bisecting plane of the bend. The ratios of the angles between the adjacent waveguide sections around the bend are approximately binomial coefficients in order to obtain a maximally flat passband.
