Broadband and compact complex ratio measuring unit
This study designs and analyzes Complex Ratio Measuring Unit (CRMU) and a Six-port Reflectometer (SPR) at a center frequency of 2.4 GHz. CRMU is designed using a compact size and wideband 3 dB-branch line coupler (BLC) and 3 dB-Wilkinson power divider with enhanced series-diamond stubs. The usage of...

The usage of these compact components leads to a compact size and improves the operating bandwidth. The idea of designing SPR is based on integrating a CRMU with 2 directional couplers along with isolator rather than a single BLC; to get a signal balance that enhances the quality of the reflection coefficient measurement.
