Analysis of S-parameters of a coupler based on the partial element equivalent circuit method

Modern electrical devices are of particular concern in terms of EMC. In this paper, a technique to obtain S-parameters using the partial element equivalent circuit (PEEC) method for a four-port coupler structure is presented. Results are compared to method of moments (MoM) solutions. The study performed shows that the results obtained through PEEC method agree well with the MoM solutions.
