Firstly the theory of the 3-D Smith chart has been explained. Then the transformation of conventional 2-D Smith chart to 3-D spherical Smith chart using ANNs has been proposed. Results have shown that proposed ANN structure learns all possible points on the surface of the spherical 3-D Smith chart with enough approximation and accuracy. Consequently, a "Neural 3-D Smith Chart" has been formed by using the ANNs in the simple MLPNN structures as the nonlinear learning machines from the input space to the output space.
