Abstract(E) | This paper explores the Poincaré distance from a continuously varying load impedance on the entire Smith chart to obtain a clearer vista on the matching circuit’s impedance behavior. We draw the impedance and constant-distant contour, and color the area within the contour. From the area, we estimate the coverage area percentage (CAP) that meets a specified distance from a given point on the Smith chart. We have done them with several types of circuits: lumped-constant (LC) matching circuits, spiral trajectory matching circuit, and clover locus matching circuit. Visualization of matching area and CAP identify which circuit we shall take in the system design. |
