摘要： A compact excitation assembly for generating a circular polarization in an antenna in particular transmit and/or receive antennas such as multibeam antennas comprises a diplexing orthomode transducer and a branched coupler and is characterized in that the orthomode transducer (21), or OMT, is asymmetric and comprises a main waveguide (22) with square or circular cross section and longitudinal axis ZZ′ and two branches coupled to the main waveguide (22) by respectively two parallel coupling slots (25, 26), the two coupling slots (25, 26) being made in two orthogonal walls of the waveguide, the two branches of the OMT being respectively linked to two waveguides (35, 36) of an unbalanced branched coupler (40), the branched coupler (40) having two different splitting coefficients (α, β) that are optimized in such a way as to compensate for the electric field orthogonal spurious components (δy, δx) produced by the asymmetry of the OMT (21).
