Problem # 1 Please simulate S (1, 1) plot on a Smith chart, and from the frequencies at which the line is multiples of a quarter-wavelength, and determine the line Zo. a)Simulation Circuit b)S(1,1) plot on a Smith chart
c)Verification of value of Zline using Line Calc tool Note: Line calc is an important tool for quick analysis and synthesis of micro-strip lines. This can be opened from Tools -> Line Calc of the main window. Please understand the usage of the tool as it is important for designing the tuning networks in Lab 2 and 3. Make R1 zero, and R2 1GOhm (open ckt line), simulate S11, and plot Z11 vs frequency. From the frequencies of the poles (singularities) and zeros, determine the wave velocity. d)Simulation Circuit
