One of the best, pratical, real world applicable RF Antenna basic design & Measurement course class for the beginner student...Keeps the student learning engaged without overwhelming, superfluous intimidating details.....Really appreciate your VNA calibration verification & connection/setup ESD & damage precautions.....
Ah Smith Chart Work of Old times, S-parameters, now we have advanced Vector Network Analyzers, and Computer Software for anyone even an Electronic Engineering Technician can use to design antennas. Keep on Learning.
I missed the name of the antenna design software. I have used Xnec2c in Linux quite a bit and 4nec2 seems to more or less work in Wine and probably fine in Windows. As far as I know they are free as in they don't cost money or expire. I don't know if they are better or worse than other options, but it is kind of funny using a GUI to basically fill in virtual punchcards.
Thanks for the class. Return loss as you mentioned is incident power/reflected power. Isn't value of RL be bigger for better matched impedance circuits?
You packed all of this into a free course. There was no fluff. Everything was easy to understand, and wonderfully presented. Thank you so much!

Thank you for this excellent presentation
Great course!
4:52 I really like Michael Ossman's saying "be a good neighbor in the spectrum" :D
NanoVNAs are fairly cheap and very powerful. Highly recommended using one of those to start with.
Thanks Karen, really enjoying your Hackaday class videos.
Many thanks Karen you lectures were both very helpful. God bless you
Great practical presentation. Thank you so much!
Thank you for sharing your knowledge!
Presented very well, thank you!
Thank you for a awesome class
Awesome, thank you! On to class 3...
Can we get these videos updated with the links in the description please?
Great class
Thank You!!

Can you provide the video link which says more about Smith chart

could you refer to some textbook where I could find solved problems related to the antenna?
May I ask if we put 6db attenuator in series with for example 3db, would it make an equivalent 9db attenuator? Thanks.

Well taught!
hi where can i find the links discussed, thanks,
RIGHT?!
dB (decibel) is not a measuring unit but a power comparison tool.
But it’s commonly used when making measurements, so it’s not incorrect to say it’s a measurement unit relative to other know quantities.
Great tutorial… right? 14:05
