The Influence of Design Features on the Electrical Characteristics of the Microwave Volumetric Strip-Slot Line Transition

Abstract

The paper studies an impact of various structure elements of the microwave volumetric strip-slot line transition on its electrical performance. The analysis has been carried out using numerical modeling methods. The results of the calculations, presented in the form of elements of the scattering matrix, allow us to draw conclusions about the permissible packing density of the beamformer elements near the microwave volumetric strip-slot line transition, and also to determine its most critical zones in which the location of the line elements strongly affects the transition characteristics. Based on the study, the possibility of using the microwave volumetric strip-slot line transition in multilayer microwave devices with a high packing density of the elements in the line is confirmed.
