Abstract
A waveguide-to-parallel-plate twist transition includes at least one waveguide-to-parallel plate twist transition element comprising an input port comprising an input waveguide portion, the input waveguide portion configured to orient an E-field of an electromagnetic wave along a first plane, and an output port comprising a multi-mode parallel plate portion, the multi-mode parallel plate portion configured to orient an E-field of an electromagnetic wave along a second plane, wherein an angle of orientation of the second plane is different from an angle of orientation of the first plane. The twist transition further includes at least one intermediate discrete twist waveguide stage coupling each input waveguide portion to the output multi-mode parallel plate portion, wherein at least one intermediate discrete twist waveguide stage is configured to orient an E-field of an electromagnetic wave along a third plane, wherein an angle of orientation of the third plane is between the angle of orientation of the first plane and the angle of orientation of the second plane.
