THE IMPEDANCE MATCHING AND CALCULATION OPTIMIZATION OF MICROSTRIP LINE ARE REALIZED BY MATLAB Basically all of them. Mainly according to the circuit diagram in MATLAB code to achieve impedance matching, and calculation optimization, and then find the length of the transmission line and impedance. Assignment 2
For this assignment, you are required to design an impedance matching network using a few
sections of 50 ohm transmission line, with capacitors connected to ground. The book shows
the hardware in Figure 8-19.
Its your choice how many capacitors and transmission line sections you use, but remember
the more you use the more complex the optimization design is (more free variables and
more complex search space).
Your load ZL you can choose, but it has to be complex, with both the real and imaginary
parts having significant values, and it does not change over frequency (this is an
approximation, in practice it will change).
The input impedance Zin leads to a reflection coefficient (relative to 50 ohm feeding
transmission line Z0) as a function of frequency. The specification of the desired reflection
coefficient and the operating bandwidth you can choose. For example a typical reflection
versus frequency is plotted in Figure 8-9 a) in the book where the bandwidth is very small.
So you need to do much better than this. What we want to see is a reflection coefficient
that has small ripple over a finite bandwidth. So the reflection coefficient must stay in a
certain range over the selected bandwidth. The range and bandwidth you can choose.
If you choose a trivial complexity design specification, you will loose marks. But don’t
choose an overly complex design specification, as then you won’t get it working because
you will need many capacitors, and the optimization will be very complex.
Finally, this project is under exam conditions, so you and your partner cannot discuss this
assignment in any way or medium with any other student, group or person – except your
lecturer. But you can make use of any written resource online. Provide a copy of your
computer code in the report. You can use any software platform to write your own code,
but you cannot use commercial impedance matching design software.
If your assignment report is found to contain material similar to other groups/student, UTAS
will process you under its new academic integrity rules and regulations. Please make sure
you understand the consequences if you are found guilty of a breach of academic integrity.
