![]() ![]() Location and length of the stub in single stub matchingĨ. Location and impedance of voltage maxima and minimaħ. Impedance to admittance conversion and vice versaĤ. The proposed course will cover calculation of following transmission line parameters.ġ. So admittance Y 2 j b and admittance Y b 1 + j b and the admittance at Y 1 is elected to be at 3 / 8. Here is the diagram for the double stub impedance: The impedance on the right has to appear purely resistive. ![]() Smith Chart allows use of normalized impedances for series circuits and normalized admittances for parallel circuits simultaneously. Im trying to understand the double stub matching impedance using Smith Chart. While working matching transmission line parameters sometime it is convenient to use impedances and other time it is convenient to use admittances. Apart from above unity real circle (complete circle) has lot of importance especially in calculation of line matching parameters. First set is real circles (complete circles) whose center lie on the horizontal straight line of the Smith Chart and second set is imaginary circles (two arc circles) which lie on the either sides of the horizontal straight line. Smith Chart consists of two sets of circles. It is also used to display multiple parameters simultaneously some of the parameters are impedance, admittance, reflection coefficient, scattering parameters. ![]() Smith Chart is circular plot and provides graphical representation of a complex mathematical equations. It is most commonly used tool in microwave and RF engineering to visualize complex quantities. Calculation of transmission line matching circuit parameters using analytical approach is lengthy process, but Smith Chart provides easy solutions to such problems. ![]()
