  • Compact orthomode transduction device optimized in the mesh plane, for an antenna
    Patent number: 7944324
    Abstract: An orthomode transducer device (D), for an antenna, comprises (i) a main guide (GP) designed for the propagation along a main axis of first and second modes having polarizations orthogonal to each other and provided with a first end coupled to a circular port (AC) and a second end, (ii) a first auxiliary guide (GA1) designed for the propagation of the first mode along a first auxiliary axis and provided with a first end coupled in series to the second end of the main guide via a series window (FSP) and with a second end coupled to a series port (AS), and (iii) a second auxiliary guide (GA2) designed for the propagation of the second mode along a second auxiliary axis, coupled to the main guide via a parallel window (FPL) and provided with a first end coupled to a parallel port (AP). The first (GA1) and second (GA2) auxiliary guides are superposed.
