The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, Sₙₙ 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.
