ABSTRACT:
A redundant transition device between a waveguide (1) and at least two redundant processing circuits (2, 3) includes two uncoupled coplanar lines (5, 6) formed one on either side of a single substrate plate (4) and extending, in part at least, into the waveguide (1). Each coplanar line (5) has a longitudinal end (17) for connection to one (2) of the processing circuits, and a longitudinal transfer end (16), adapted to channel an electromagnetic wave between the waveguide and the slots (21, 22) of the coplanar line. Each coplanar line (5, 6) is provided with a phase shifting element (25, 26), for inverting the phase of an electric field on one side of the central transmission strip (7, 10) of the coplanar line.
