Title of the Tutorial Session (CICT 2024):
A Fully Symmetrical Planar Smith Chart: An Elegant Approach to Microwave Active/Passive Circuits Design
Abstract:
The Smith chart is a fundamental tool in RF/Microwave engineering for designing, analyzing, and developing RF/Microwave circuits and components. However, the conventional 2D Smith chart, developed in 1931, has limitations. It cannot plot negative resistance parameters and whole reactance curves within a finite space, and even if a point with negative resistance is mapped back into the unit circle by taking the mirror image, it shares the same space as impedances with positive resistance, which is not visually pleasing. To address these concerns, in 2007, C. Zelley proposed a spherical Smith Chart. Later in 2011, A Muller, et al., extended the spherical Smith Chart to a 3D Smith Chart based on the Riemann Sphere. While this approach can plot both positive and negative resistance and whole reactance curves onto a finite 3D surface, it requires CAD software to use it as a design tool or visualization aid for the RF and microwave community.
In 2023, a Planar Mercator Smith Chart (PMSC) is proposed to address the limitations of previous Smith Charts. The PMSC utilizes the Mercator projection principle inspired from Earth’s Mercator map to elegantly represent all resistance and reactance on a 2D flat surface in a fully symmetrical way, revealing the internal symmetries between positive and negative values of the resistance. The VSWR and/or constant reflection coefficient magnitude scales are created using web mapping features of Mercator projection such as loxodromes, while the longitudes are projected as vertical lines perpendicular to the equator to provide scales for reflection coefficient angle, wavelength toward the generator and/or load. Unlike the 3D Smith Chart, the PMSC does not require CAD software for use it as a design tool or visualization aid, and it can be a useful graphical chart for solving microwave problems involving any type of load. The proposed PMSC's topological properties are utilized to analyse and solve one-port microwave oscillator load-matching circuits, stub matching, and other design problems to be discussed during the talk.
