Abstract:
The design and fabrication of an Ultra broadband
OMT-polarizer is discussed here. The principal advantages of
this topology relay on both the instantaneous bandwidth and
the axial ratio improvement. Experimental measurements
exhibit very good agreement with the predicted results given by
Mician μwave wizard. The structure provides an extremely flat
axial ratio (AR< 0.4dB) and good return losses >25dB at all
ports over the extended Ku band (60%). Moreover, yield
analysis and scaling properties demonstrate the robustness of
this design against fabrication tolerances.
