COMPACT BI-POLARIZATION AND MULTI-FREQUENCY RADIOFREQUENCY EXCITATOR FOR ANIMAL PRIMARY SOURCE AND ANIMAL PRIMARY SOURCE EQUIPPED WITH SUCH A RADIOFREQUENCY EXCITATOR

摘要

The radiofrequency exciter consists of a junction (10) having an axial access (15) intended to be connected to a radiating horn, at least four lateral accesses (21, 22, 23, 24) and at least four frequency filters ( 11, 12, 13, 14) respectively associated with the four lateral accesses, the junction comprising, in series, a first coupling cavity (1) provided with two coupling slots (31, 32) able to take a vertical polarization and a second coupling cavity (2) provided with two coupling slots (33, 34) capable of taking a horizontal polarization, the four frequency filters being directly connected to the four respective coupling slots, the first coupling cavity comprising a cross-section having a constant vertical dimension and a decreasing horizontal dimension between the axial access (15) and a transverse outlet opening (16) of the first coupling cavity (1).
