Abstract (en)

The device has a waveguide (5,5') with at least one phase shifter (11) close by and at least one decoupling or compensating element (19,19') in the guide to improve and/or match the decoupling and/or to reduce the reflected energy of the incident electromagnetic waves. At least one additional decoupling or compensation element (19,19') is arranged in the guide offset w.r.t. the phase-shifting plane about the propagation direction or central longitudinal axis (25).

Abstract (de)
