Abstract
A major expansion of the range of wave impedances provide 3D electromagnetocrystalline heterogeneities (ECIs), combining heterogeneities in metallized surface, dielectric and the signal surface of microstrip line. As consequence 3D ECIs as quasi-lumped reactive elements ensure a significant reactivity increasing compared with the conventional structures. The inductor and capacitor may be combined in the construction of ECI, named combined. The constructions of combined ECIs are proposed. As a model of the first approximation for combined ECI a 1D model based on transmission line is considered. With the help of 1D model analytical results for combined ECI are obtained. A comparison between the efficiency of single and combined ECI using 1D and 3D models is made. 3D modeling is performed in the program package CST Microwave Studio. Experimental and calculated transfer characteristics of electromagnetic crystalls (ECs) on the basis of single and combined ECIs are presented. Experimental and calculated values of the forbidden zone minimums for ECs on the basis of single and combined ECIs are equal -36, -38, -64 and -75 dB, respectively.
