TE(11) modes in straight and curved circular waveguide with 'deformed' cross-section
Abstract
The two polarisations of TE(11) modes are shown to be nondegenerated in a circular waveguide when its cross-section is 'conveniently deformed', so the crosspolar discrimination is improved in such a curved guide. This permits the use of this structure as an antenna feeder at frequencies about 12 GHz.
