![]() Inductance characteristics are on the top half and capacitance characteristics are on the bottom half.Check out this SMITH chart program and try creating a few solutions with the building blocks:Fritz DellspergerThis program free version is limited to a few components. The Smith chart consists of a plot of the normalized impedance or admittance with the angle and magnitude of a generalized complex reflection coefficient in. of the form z2 jx, and hence the input admittance of the loaded section. The fish is swimming there exactly in the MIDDLE.In a boat, You are siting in the middle of the pond and facing toward the RIGHT side of the pond, which is the OPEN sea.Another fish having a very SHORT tail suddenly passes on the LEFT side.You have a COILy hair on TOP of your head and unfortunately your CAP fell off and sank to the BOTTOM.So in other words the center horizontal line is pure resistance, 0 ohms on the left, (typically) 50 ohm point in the center and open (Infinite) on the right. Matching circuits can be easily and quickly designed using the normalized impedance and admittance Smith chart (Z and Y charts). Since the stub section is lossless, its input impedance must be purely reactive, i.e. ![]() The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, Sāā scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability, including mechanical vibrations analysisAlthough the Smith Chart looks quite scary at first, it really is not.The smith chart will tell you a great deal about antennas and resonate circuitry.Here is a simplistic explanation of the area of a Smith chart.Visualize the CIRCLE area of a Smith chart as a pond and FIFTY-OHM as a fish.
