Modeling of transmission lines with textured ground planes and investigation of data transmission by generating eye diagrams

Abstract: In this work, data transmission in transmission lines containing textured ground planes in the power distribution network is investigated. A lumped element model is developed to generate eye diagrams and circuit simulations are compared with measurements. A circuit model for a transmission line with an EBG ground plane is introduced. The circuit model for the EBG structure is developed based on using LC components and considering each patch as a parallel-plate transmission line. This modeling strategy allows including two important features to the individual LC stages representing the EBG surface: coupling to the signal line, and transverse loading of adjacent patches in the EBG structure. The circuit model parameters are calculated by using closed-form relations and applying the physical dimensions of the structure-under-test. The proposed model is employed to generate the scattering-parameter graphs and eye diagrams, which are compared with full-wave simulations and measurements to ensure validation of the results in both frequency and time domains.
