As normal the accuracy you need for this is dependent upon the required frequency. If we design a matching network it will be assumed that this is where we place our components. We must be very careful to understand the calibration plane of tour antenna. However I will highlight one critical point. I won’t go into detail here about how to measure an antenna as this was covered in my previous posts. The Device Under Test could really be any device, but as I am an antenna geek, lets assume its an antenna. Once you get to grips with the basics here, you can always experiment in QUCSstudio with alternate components. However it is possible to use alternative components such as transformers, transmission lines, or even resistors as part of an matching network. Of course, I had totally forgotten!!! But lets go through it again.Ī matching network is normally a network of inductor or capacitors selected to convert from one impedance to another. I was asked in the comments about exactly to do this. This could be used to quickly design antenna matching networks for instance. In my last blog post I alluded to the fact that you could take s1p touchstone files generated by nanoVNAsaver and use this to automatically calculate/simulate a matching network in QUCSstudio.
