Polarización circular ultra-ancha banda para aplicaciones satélite

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.
