AI Technical Summary

Technical Problem

Existing single-reflector MFB antennas face challenges in compactness and mechanical interdependence of distribution modules, making assembly difficult and limiting integration of additional functionalities like deviation measurement.

Method used

A compact reciprocal hybrid E/H combiner-divider is introduced, comprising a primary waveguide and secondary waveguides with internal conductive elements, allowing efficient coupling and separation of electromagnetic waves, and integrating deviation measurement functions without additional hardware.

Benefits of technology

The solution simplifies the production of distribution modules, reduces space requirements, and enables integration of deviation measurement functions, enhancing the assembly and functionality of single-reflector MFB antennas.

Abstract

The invention relates to a 1:4 reciprocal compact E / H hybrid combiner-divider, comprising at least one primary waveguide (41) and two secondary waveguides (42, 43) forming an integral structure configured such that the primary guide (41) has a first end forming an input / output port (48) and a second end defining an opening (61) and such that each secondary guide has two ends forming two input / output ports (44-45, 46-47), as well as a side opening (62, 63) provided on one of the small side faces. The secondary guides (42, 43) are arranged so as to have a common side wall (51). They are arranged facing the main waveguide in such a way that the side openings (61, 62) face the opening (61) formed by one of the ends of the main waveguide (41) and that the common wall (51) is aligned with the median axis of the opening (61) of the main waveguide (41).
