Abstract: 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, an input end 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, 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 connected to a single-pole switch or combiner transmitting signals from either or both of the two modules downstream of the device.
