Abstract :
The two polarisations of TE11 modes are shown to be non-degenerated 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.
