Abstract
A microwave apparatus comprises a waveguide section including a stepped septum. The septum is positioned so as to divide the waveguide into two channels. The steps comprise a plurality of first steps which advance progressively in one direction and at least one second step, or the equivalent, which follows the first steps and which returns in an opposite direction. The invention is intended to enable the production of a circularly polarized microwave signal without requiring the use of phase adjustment techniques.
Claims5
A junction between three waveguides in which one of the waveguides is formed in a channel of uniform cross section and is divided into two parallel waveguide channels so as to define the other two of the three waveguides by an asymmetrical stepped septum comprising first step means including a plurality of first steps which advance progressively in one direction and second step means including at least one second step which follow the first step means and which returns in an opposite direction.
