Abstract
This article presents the complex ratio measurement unit (CRMU) design formed by enhanced 3-dB branch-line couplers (BLCs), which are placed symmetrically. The first CRMU is formed by four wideband 3-dB BLCs implementing Defect Ground Structure (DGS) and stub impedance techniques that operate over the frequency of 2.5 to 4 GHz. Meanwhile, the other CRMU is formed by four reduced size of enhanced two-section microstrip-slot BLCs with tight coupling of 3-dB over frequency of 2 to 5 GHz. The performances of the CRMU designs are observed and analyzed. The BLCs and CRMUs are designed using CST Microwave Studio. While, the S-parameter performances of the CRMUs are analyzed using Keysight’s Advanced System (ADS) software.
