An improved design of wideband Wilkinson power divider with stubs concerning operating frequency of 2 to 7 GHz is presented in this paper. Power divider is designed by adding stubs at transmission line of Port 1, 2 and 3, which the position of stubs is studied for wideband application. CST Microwave Studio is used to design the proposed power divider and(More)
A wideband six-port Complex Ratio Measuring Unit (CRMU) design is presented in this paper. CST Microwave Studio is used to design the CRMU by integrating one in-phase Wilkinson power divider with stubs and three 90° microstrip-slot two-section branch-line couplers (BLCs). Wilkinson power divider is improved by implementing additional stubs at(More)
A new design of compact ultra wideband (UWB) six-port network by using ground-slotted technique is presented in this paper. The proposed six-port network is accomplished by constructing four in-phase two-section power dividers and two 90o power dividers by using CST Microwave Studio 2010. The presented result shows that the proposed UWB six-port network(More)
This paper proposes a new branch-line coupler with slots operates from 3.5 GHz to 4.7 GHz frequency band. The proposed design concerns the addition of slotline at the ground plane underneath the right and left branch of the coupler. The design and parametric study of the proposed coupler are performed using CST Microwave Studio. The length and width of(More)
