Γ = u + jv = Rejθ, where R is the radius and θ is the angle of incidence.įrom the last two equation, we can see that there is one-to-one correspondence and for every Z we can obtain a unique Γ. The above equation can also be written as Γ = / for r lies between 0 and ∞, x lies between -∞ and +∞. Γ = (ZL-1) / (ZL+1) as Zo takes constant values such as 50Ω, 100Ω, etc. Therefore, Reflection coefficient can expressed as Normalized impedance, Z = ZL/ Zo = r+ jx, where r = R / Z0 and x = X / Z0. This is because the behavior of the transmission line depends on load impedance as well as characteristic impedance. Normalized impedance is used for plotting on Smith chart. Γ = (ZL - Zo) / ( ZL + Zo ) where, ZL is load impedance and Zo is the characteristic impedance of transmission line, a constant. Therefore, from the fig., gamma can be expressed as, The amount of reflected wave depends upon the mismatching of the source and load impedances. The ratio of the voltage of reflected wave and the voltage of incident wave is known as the reflection coefficient. If there is impedance mismatching, part of the energy in the incident wave is reflected back giving rise to a standing wave. transmitter to antenna or antenna to receiver), the impedance of source must be equal to the impedance of load. While transferring the RF waves on a finite transmission line, for maximum power transfer from source to load (i.e. These are the impedance matching circuits. Transmission lines are the circuits that deliver power from a transmitter to an antenna and from an antenna to a receiver.
The Tkinter module most powerful GUI-based widget and it has followed with the Tk interface also it has most advanced library methods in the python.The Smith Chart is the graphical representation of a complex mathematical equation. It has more number of global methods hence Combobox() also one of the widgets and globalizes methods it can be used to directly on the specific functions and behavior of the application. Variable name=ttk.Combobox(variable name, width=, text= ) It has its own syntax and default parameters.
#CHARTSMITH GAS CODE#
The above code is the basic syntax of the Combobox Tkinter library. We have called the UI items like label, textbox, etc based on the requirement we will proceed it for further steps to enhancement the application. The Tkinter module has a different set of widgets in the library this package has a set of built-in functions that have been used for covering the UI parts in the web application. It has the most interactive and advanced library it can be calculated the functionalities for the time, speed and weather calculations, some scientific calculations, etc even though some AI-based functionality also covered in these widgets. The UI widget has buttons, views, scroll box, list box, combo box, etc mostly button will be covered the UI part to navigate the web pages or applications.
Once we clicked the button it operates and works the backend areas code that can be covered to the user-defined logic. When we use these combo boxes lists the user can be chosen the entry values and these entries are scrolled down using the drop-down option and the arrow symbol will be used on the left side of the area that will drop-down the values and menus are choosing and showing the choices. And these choices are clicked by the user if the user is not choosing any values it takes the default value based on the code logic on the front end and backend. If the user selects any values of the combo list box again the value will be replaceable if the user needs it.
