Questions & answers
What is Smith chart and how does it work?
In the complex reflection coefficient plane the Smith chart occupies a circle of unity radius centred at the origin. In cartesian coordinates therefore the circle would pass through the points (+1,0) and (−1,0) on the x-axis and the points (0,+1) and (0,−1) on the y-axis. with a, b, c and d real numbers.
What is the center of Smith chart?
The center of the Smith Chart is the point where the reflection coefficient is zero. That is, this is the only point on the Smith Chart where no power is reflected by the load impedance. The outter ring of the Smith Chart is where the magnitude of is equal to 1.
What is length of Smith chart?
The Smith Chart allows easy calculation of the transformation of a complex load impedance through an arbitrary length of transmission line. It also allows the calculation of the admittance Y = 1/Z of an impedance. The impedance is represented by a normalized impedance z. Once around the circle is a line length of l/2.
What is Smith chart explain in detail?
The Smith chart, invented by Phillip H. Smith (1905–1987) and independently by Mizuhashi Tosaku, is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits.

We zoom in aMoreThis means that our reactance axis lies along the circumference of the Smith chart. If. We zoom in a bit we can see the values of normalized reactants indicated along the circumference of the chart.
How do you make a Smith chart?

We'll assume the standard 50 ohms so our normalized impedance is 2 plus 1.5 J.
