Design of 3dB Directional Coupler for Ka-Band Input Multiplexer of Satellite Payload Applications

摘要

In this paper, we have studied that the easily implementation of low insertion loss, good matching, and high isolation of 3dB directional coupler required in Ka band Input Multiplexer, in a type of Riblet Short Slot (RSC) using Coupling Matching Stub (CMS) and it successfully applied to Input Multiplexer (IMUX) for satellite applications.
