Abstract
A redundant transition device between a waveguide () and at least two redundant processing circuits () includes two uncoupled coplanar lines () formed one on either side of a single substrate plate () and extending, in part at least, into the waveguide (). Each coplanar line () has a longitudinal end () for connection to one () of the processing circuits, and a longitudinal transfer end (), adapted to channel an electromagnetic wave between the waveguide and the slots () of the coplanar line. Each coplanar line () is provided with a phase shifting element (), for inverting the phase of an electric field on one side of the central transmission strip () of the coplanar line.
