Abstract (en)
[origin: EP0872910A2] The coupler has a coupling chamber (KR) with two hollow conductors coupled to each end. The dimensions of the coupling chamber are selected so that the higher wave types H11 and E11 can be propagated as well as the fundamental wave type H10. Coupling apertures (KB1-KB2) are arranged between the coupling chamber and the individual hollow conductors. The height of the coupling chamber corresponds to at least 2.5 times the height of a coupling aperture (b).
