Design of Wideband Impedance Matching for Waveguides with Inhomogeneous Dielectrics

In this study, synthesis of multilayer dielectric structures is proposed to provide broadband impedance matching with waveguides. The dielectric values of the layers that fills the cross-section of the waveguide are predetermined for practical usability. It is aimed to minimize the back reflection by optimizing the unknown layer thickness values. The obtained results show that a wideband impedance matching can be performed by compact structures. Keywords—impedance matching, optimization, dielectric loaded waveguides.
