Webpling. In [7], couplers were designed in a multilayer structure with two- and three-strip couplings. These approaches rely on broadside coupling through a dielectric layer between the microstrip lines. It is also possible to use an original or unfolded Lange coupler [1, 3] for 3-dB coupling. This design concept is based on using WebLange Coupler can be widely used since it readily provides a broadband 90° phase split. In comparison, the branch line coupler has a narrow bandwidth and has an inconvenient shape, which is very waste full of chip space. The advantage of this design is that we can use Lange Coupler as a combiner and 90° phase shifter thus reducing component ...
