Problem solving Reflection coefficient &SWR Syllabus Transmission Lines and RF Systems UNIT I TRANSMISSION LINE THEORY General theory of Transmission lines — the transmission line — general solution — The infinite line — Wavelength, velocity of propagation — Waveform distortion — the distortion-less line — Loading and different methods of loading — Line not terminated in Z0 — Reflection coefficient — calculation of current, voltage, power delivered and efficiency of transmission — Input and transfer impedance — Open and short circuited lines — reflection factor and reflection loss. UNIT II HIGH FREQUENCY TRANSMISSION LINES Transmission line equations at radio frequencies — Line of Zero dissipation — Voltage and current on the dissipation-less line, Standing Waves, Nodes, Standing Wave Ratio — Input impedance of the dissipation-less line — Open and short circuited lines — Power and impedance measurement on lines — Reflection losses — Measurement of VSWR and wavelength. UNIT III IMPEDANCE MATCHING IN HIGH FREQUENCY LINES Impedance matching: Quarter wave transformer — Impedance matching by stubs — Single stub and double stub matching — Smith chart — Solutions of problems using Smith chart — Single and double stub matching using Smith chart.
