![]() ![]() The dielectric and loss tangent properties of the substrate are manipulated using different weight ratios of filler, while PVA keeps the flexibility features. The structural (XRD) and morphological (FESEM) investigation allows for being used as a flexible substrate. The developed flexible composite substrate is built using PVA glue and a micro-scale of Mg–Zn ferrite nanoparticle powder, while this powder is used as filler. A stove-shaped metamaterial unit cell is designed and fabricated on a flexible substrate, and the microwave performance of the structure is investigated. This article reports the preparation of MgxZn(1-x)Fe2O4 ferrite-based flexible substrate using the sol–gel synthesis method. ![]() Since there's no scientific or experimental result in the literature for this kind of complicated structure, it was necessary to perform simulations using HFSS Commercial Software. To control the electromagnetic coupling, we place a thin layer of ferrite between the (CRLH) CPW and the (CSRRs) resonators. On the lower ground plane, we use defected ground structure technology (DGS) to engrave two (CSRRs) offered with different shapes and dimensions. Our solution consists in using the electromagnetic coupling between the composite line (CRLH) CPW and the complementary metamaterial resonators (CSRRs).The (CRLH) CPW is composed of two resonators, each one has an interdigital capacitor (CID) and two short-circuited stubs parallel to top ground plane. In this paper, we propose a solution to improve the electrical qualities of the dual-band bandpass filter. Several studies and solutions are proposed to have good qualities of filtering. In the field of microwave filtering, the electrical qualities of the filter represent the main objective of the design. ![]()
