Smith Charts - Antenna Theory
In this tutorial, we will introduce and explain Smith Charts, and then given an introduction to impedance matching. We will then use the Smith Chart to perform impedance matching with transmission lines and lumped components (capacitors and inductors).
•Philip Smith of Bell Laboratories developed the “Smith Chart” back in the 1930”s to expedite the tedious and repetative solution of certain rf design problems. These include: •Transmission line problems • Rf amplifier design and analysis •L-C impedance matching networks •Plotting of antenna impedance •Etc.

The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and ...
The Smith Chart - Intro to Impedance Matching and Series L …
On this page, we'll start the beginning of impedance matching, by illustrating the effect of a series inductor or a series capacitor on an impedance. The Smith Chart makes this easy to visualize. Impedance Matching is the process of removing mismatch loss.
•The Smith chart –Refresher: Visualization of a complex impedance in the frequency domain –Definition of the Smith chart, mapping the complex impedance / admittance plane with the complex reflection coefficient –Basic facts and important points on the Smith chart –Examples for a RL and RC series circuit,
The Smith chart is a useful graphical tool to convert between impedances and reflection coefficients. It may also be used to solve impedance-matching problems.
The Smith Chart • Superimposes constant Γ, r and x circles • We can quickly relate normalized line impedance to its corresponding reflection coefficient
Introduction to the Smith Chart - Part 1 - CIRCUIT DESIGN,INC.
Introduction. The Smith Chart is a useful graphical tool to the RF design engineer who needs to amongst many things, analyse impedances or design matching circuits. Rather than perform many tedious calculations by hand, results can be easily visualised on such a chart, making the RF design engineer's life much easier.

This page presents a video explaining the Smith Chart, Smith Charts and related concepts, including impedance matching, mainly applied to antennas and antenna theory.
The Smith chart is based on a polar plot of the voltage reflection coefficient G. The outer boundary corresponds to |G| = 1. The reflection coefficient in any passive system must be. Γ ≤ 1. All impedances on the Smith Chart are normalized. This is usually done with respect to the characteristic impedance of the transmission line Z0.
