ABSTRACT
Matching networks when designed with lumped elements are implemented using a ladder network structure. In the design of matching networks, there are several important parameters such as bandwidth and quality factor of the network. A transmission line is a distributed-parameter network, where voltages and currents can vary in magnitude and phase over the length of the line. Transmission lines usually consist of two parallel conductors that can be represented with a short segment of Δz. The Smith chart is a conformal mapping between the normalized complex impedance plane and the complex reflection coefficient plane. It is a graphical method of displaying impedances and all related parameters using the reflection coefficient. The ZY Smith chart gives the ability to implement both impedances and admittances on a single chart. It is a power chart, and it enables designers to make impedance transformation and matching using a unique graphical display when the components are connected in series or in shunt.
