A magic tee microwave junction comprising: an E-plane tee junction includes a difference arm along a first axis (Ox) in a reference plane (xOz) and two collinear arms that are symmetric about the reference plane, an H-plane tee junction comprising a sum arm along an axis (O'z′) orthogonal to the first axis in the reference plane and two collinear arms that are symmetric about the reference plane, two first waveguides that are symmetric about the reference plane, connected to the ends of the collinear arms of the junctions, two waveguides that are symmetric about the reference plane and connected to the first waveguides. A power divider, to a beamforming network and to an additive manufacturing production method is also provided.

Wideband magic tee microwave junction

An orthomode transducer and to a satellite transmission chain includes the orthomode transducer, for transmitting a first signal and a second signal in orthogonal propagation modes. The transducer comprises: a primary waveguide with a square or rectangular cross section, two guided access means having firstly a free end via which the first signal and the second signal are respectively injected or recovered, and secondly two arms connected to the primary waveguide. Each guided access means comprises a junction configured so as to connect the free end to the two arms of the guided access means, the two arms of each guided access means being connected to the primary waveguide at two off-centred locations on one or more sides of the primary waveguide symmetrically about an axis of symmetry of the primary waveguide.
