The Performance of Rectangular Microstrip Structure by Applying the Cole-Cole Diagram Concept

Abstract—This research provides a method for analyzing the performance of a rectangular microstrip structure by adopting Cole-Cole diagram. A “reactive relaxation” concept is introduced to represent the frequency-dependent characteristics of a microstrip. Included in the algorithm are relevant considerations relevant to the substrate dielectric and strip-line conductor losses. The proposed concept is used to analyze the microstrip structure performance. The proposed models are set up for use in computer-aided microstrip design and are fully compatible with the needs and trends of modern computer-aided microstrip antenna design and RF integrated circuit (RFID) design.

Index Terms—Dielectric substrate, cole-cole diagram, frequency-dependent, microstrip structure.
