Transmission-line impedance problems and to illustrate how RF parameters behave at given frequencies still used for antenna problems and equipment displays. The radiating element of the proposed antenna consists of. This brief tutorial explains what the Smith chart is. A main goal of antennas impedance matching is compensating for capacitive or inductive reactance and transforming the impedance as. The Smith chart, named after Phillip Hagar Smith, is a graphical aid to solving Due to the difficulties in learning and teaching microwave technology and antenna, we introduced the Smith chart as a computer-aided experimental teaching. This paper presents a compact microstrip patch antenna at operating frequency of 2.5 GHz. The Smith chart is one of the most important tools in understanding RF impedance and matching networks. To compare smith chart plotting values with the manual computation. To plot impedance, admittance, reflection coefficient and SWR. the observation point and the terminals of the device under study, whether that be an antenna or a transistor. For example, the normalized impedance for a loadZ L 73 + j42 on a50 transmission line isZ LN 1.46 + j0. Warning: TT: undefined function: 32 Laboratory Exercise 4 Smith Chart Plotting (Impedance, Admittance, Reflection Coefficient and SWR) OBJECTIVES: At the end of the exercise, the students should be able to: To know the basics of Smith Chart. The Smith Chart works with normalized impedance and admittance, where normalization is made with respect to the characteristicimpedance of the transmission line.
