A device for transmitting electromagnetic signals across a structure including functional modules organized so that two-for-one redundancy is obtained, in the case of signals that are transmitted by electromagnetic waveguides, includes a waveguide (6), an input end (IN) of which receives signals intended to be fed to one or the other of two functional modules organized so that two- for-one redundancy is obtained, and the other end of which is short circuited. It includes two electric field sampling units (8, 8'), each of which is adapted to feed one of the modules and which are disposed at respective distances from the short circuited end of the waveguide that are equal to one quarter of the wavelength of the signals transmitted by the waveguide or an odd number multiple thereof. Each module has an output (01 or 01') connected to a single-pole switch (12) or combiner transmitting signals from either or both of the two modules downstream of the device.
Le dispositif comporte un guide d'ondes (6) à une entrée (IN) duquel sont reçus les signaux destinés à être appliqués à l'un ou l'autre de deux modules fonctionnels (l, l') organisés pour permettre l'obtention d'une redondance en deux pour un. Le guide a une autre extrémité qui est en court-circuit et il est équipé de deux organes (8, 8') de prélèvement de champ électrique, prévus chacun pour alimenter un des modules. Ces organes sont respectivement disposés à des distances de l'extrémité en court- circuit du guide qui sont égales au quart ou à un multiple impair du quart de la longueur d'onde des signaux transmis par ce guide. Chaque module est par ailleurs relié par une sortie individuelle (01 ou 01') à un élément de recombinaison (12), de type commutateur unipolaire ou combineur, transmettant en aval du dispositif les signaux parvenant de l'un et/ou de l'autre des deux modules.
