Abstract (en)
[origin: EP0395888A2] 1. Coupling aperture 2.1 It is intended to specify a coupling aperture in which the coupling openings are arranged such that desired couplings are effected while very heavily parasitic couplings are reduced as much as possible. 2.2 This object is achieved in that coupling openings (K1, K2) are arranged in the coupling aperture (KB) such that couplings take place via said openings for two mutually independent wave modes and such that coupling of the two wave modes takes place via at least one of the coupling openings and a coupling of equal magnitude, but in the opposite sense, likewise takes place via at least one of the other coupling openings, so that these two couplings in opposite senses cancel one another out. <IMAGE>
