Fabrication and Characterization of Directional Couplers as Power Dividers
IPTEK Journal of Proceedings Series, 2019 This paper is about directional coupler fabrication results in a slab structure with a substrate in the form of acrylic glass, a film of nano SnO 2 , and cladding in the form of methyl methacrylate (MMA). The length of the interaction area (Lc) directional coupler of the fabrication result is 5 mm with a gap width (g) of 0.353 mm.

Comparison of the broadband performance of in-phase power dividers and 0�/180� directional couplers [PDF]
Microwave and Optical Technology Letters, 1999 A comparison of the broadband performance of four different microwave 0°/180° directional couplers and two in-phase power divider/combiner networks is presented. The analysis of the six networks is presented, and is followed by their performance characteristic in terms of S-parameters.

Power divider based on vertical elliptical directional couplers with increased isolation and bandwidth [PDF]
The Journal of Engineering, 2019 In this study, a novel high‐isolation wideband divider based on multi‐layer elliptical defected ground structure coupler is presented along with its analytical theory and design procedure. The proposed divider could be conveniently applied for high‐ power applications with less loss for the absence of isolation resistors.
