'BackgroundColor', 'Position',)Īnnotation(container, 'arrow',) Calculate the Stub Location and the Stub Length for the Output Matching Network Then we have made an inductance thus we are in the upper half of the Smith-Chart. 'HorizontalAlignment', 'center', 'FontSize',8. en adding a section of line we have to turn clockwise: assume we are at -1 (short circuit) and add a very short piece of coaxial cable. These reflection coefficients are measured at the amplifier interfaces.Ĭircle(amp,freq, 'Gamma',abs(GammaL),hsm) The routine plots normalized impedance in a Smith chart, i.e. Calculate and Plot the Complex Load and Source Reflection CoefficientsĬalculate and plot all complex load and source reflection coefficients for simultaneous conjugate match at all measured frequency data points that are unconditionally stable. Plots normalized impedance in a Smith chart. This example uses the YZ Smith chart because it's easier to add a stub in parallel with a transmission line using this type of Smith chart. At this location, the stub will negate the transmission line susceptance, resulting in a conductance that equals the load or source terminations.

Im fairly new to matlab environment and not sure how to achieve it. along transmission lines using the Smith Chart (by professor Carlo Riva). I need to plot Smith chart, having frequency, VSWR, reflection coefficient and phase.

Movement along a transmission line is equivalent to traversing a circle centered at the origin of the Smith chart with radius equal to a reflection coefficient magnitude.Ī single transmission line stub can be inserted at the point on a transmission line when its admittance (transmission line) intersects the unity conductance circle. Platforms: Matlab (R2007a and following versions) Windows XP and Windows 7. With the aid of a Smith chart, calculate the position andlength of a short-circuited stub matching a XXXXXXXXXXj120)-0 load to a 300-0transmission line.

Posting homework assignments is not prohibited if you show that you tried to solve it yourself.The center of the Smith chart represents a normalized source or load immittance. These are generally termed as the usual type of smith charts as they correspond to impedance and functions in an excellent way even with huge loads constructed of many series components where these are the crucial components in the impedance matching and for other RF corresponding operations.

Either the example compiles cleanly, or causes the exact error message about which you want help.Īvoid posting a lot of code in your posts. Plot S11 on a Smith plot for a reference impedance of 50 ohm. Calculate the complex s-parameters of the dipole antenna from 60 MHz to 90 MHz, with an interval of 150 kHz. Create a strip dipole antenna on the Y-Z plane. Plot the reflection coefficients of a dipole antenna. Include the error you get when running the code, if there is one.Įnsure your example is correct. Add S-Parameter Data to Existing Smith Plot.
