OMT TYPE BROADBAND MULTIBAND TRANSMISSION-RECEPTION COUPLER-SEPARATOR FOR RF FREQUENCY TELECOMMUNICATIONS ANTENNAS

摘要

The present invention, microwave-frequency antenna for telecommunications OMT ("OrthoMode Transducer multi-band having a ") of the type wideband (Wide Band) transmission-present invention relates to a separator-receiving coupler. These couplers, ports for all radio frequency (P1), a body, and a port (P2) for propagating the high frequency band, these three portions are coaxial with, the port and the body, and are produced in the body and each waveguide is connected, comprising the (24A) coupled to a broadband low-frequency band slot for the radio wave, its body (24) for combining the two ports whose profile varies with multi polynomial law, the largest cross-section It characterized in that it has a shape of rotation to decrease a constant port (P1) from the port with the smallest cross section (P2). These couplers, broadband bandwidth - can operate to a coupling and separation (these couplers full use of the separator 2 is an octave or more), of two or four wideband coupling slots are linear and circular polarizations after recombination it is necessary for propagation. ;
