摘要
the cd for the generation of excitation polarizationan antenna includes a circular transducer and a orthomode diplexantbranching coupler, and is characterized in that the transducer orthomode(21).as wto is asymmetrical and has a main waveguide (22)square or circular longitudinal axis (zz ') and two branches togetherthethe waveguide core (22) with two slots (25, 26)couplingin parallel, the two coupling slots (25, 26) is carried out in twothe wallsa rectangular wave guide, the two branches of the organization being respectively.related to the two waveguides (35, 36) of the coupler branches out(40).the coupler has two branches (40) partition coefficients(. alpha.,. beta.) andoptimized to compensate for parasitic components orthogonal(.delta.y..delta.x) electric field caused by the asymmetry of the world tourism organization (21).application in particular to the transmitting antennas and / or receiptfor example, the multi beam antennas.
