The theoretical investigation of waveguides having non-uniform cross-section is an attractive and challenging problem which arises serious interest. In this paper, we develop the analysis of laminated multilayered 3D-waveguide, by the three following steps: (i) Coupled Mode theory (CM) is generalize
Figure Return loss of gap-coupled circular patch antenna derived by using three methods 4.0 and 1.6 mm, respectively. The cell size along the thickness of the substrate is 0.4 mm, while it is 0.6965 mm along the other two directions. Figure compares the result for the return loss of the antenna de
