Miniaturization of the Volumetric Strip-Slot Transition and Investigation of its Matrix of S-parameters

The application of the volumetric strip-slot transition is relevant for the implementation of contactless microwave power transmission device or microwave filtering device. This statement can be confirmed by several arguments. Firstly, it is due to compactness of the volumetric strip-slot transition that achieved by the multilayer arrangement of its functional parts. Secondly, it is due to the frequency-selective properties of the volumetric strip-slot transition which can be classified as band-pass. And thirdly, the volume-modular principle of its design makes it possible to ensure the replacement of individual components of the volumetric strip-slot transition. It allows to ensure high functional flexibility of the volumetric strip-slot transition. At the same time an important line in the development of wireless electronics is miniaturization of devices that operates in the microwave frequency range. In this case the issue of miniaturization of the volumetric strip-slot transition can be solved with the use of a U-shaped slot resonator. The purpose of this article is to present the results of theoretical and experimental researches of the matrix of S-parameters for the miniaturized volumetric strip-slot transition. The matrix of S-parameters of the volumetric strip-slot transition is found by the numerical simulation with a rigorous electrodynamics formulation. Experimental results obtained on the volumetric strip-slot transition sample are in the good numerical agreement with the simulated results.
