Multi-Objective Design of Transmission Line Referenced to Meshed Ground Planes by Preference Set-based Design

In the design of transmission line, sometimes it is required to pursue a solution which satisfies simultaneously multiobjective (electrical, mechanical, and thermal) performances even including conflicting requirements. This paper newly attempts to propose a multi-objective satisfactory design method, Preference Set-Based Design (PSD), to the design of a transmission line referenced to a meshed ground plane. This work demonstrates that PSD method is applicable for multi-objective design of transmission line from the viewpoint of SI and EMI performances. The design parameters of a simple transmission line referenced to the meshed ground plane, which satisfy required performance, are obtained successfully in ranges by PSD. The validity of the proposed method is demonstrated.
