Abstract
An embedded coplanar waveguide suitable for high-speed digital applications is presented and described. The main goal is to examine if the proposed design can be an alternative method of using suspended stripline in constructing multilayer PCBs. The idea was to eliminate the separate dedicated ground reference layers, and by reducing the layer count, the manufacturing cost will be reduced. In this research, five different cases of designing CPW lines were designed and simulated using ANSYS Electromagnetics software. Equations and numerical analysis of performance of CPW lines were provided and explained. In addition, different techniques were used to reduce the inter-layer crosstalk between layers. At 15 GHz, CPW lines observed a maximum of (-20 dB) crosstalk between all ports. The simulation results indicate that the proposed design can be applied and used on multi-layer PCBs once fully tested and validated.
