Understanding the Smith Chart

The Smith chart is one of the most important tools in understanding RF impedance and matching networks. This brief tutorial explains what the Smith chart is and how it can be used to represent complex impedances.

Every University Teacher must watch this before teaching to students. Perfect, clear and neat way to explain. I request your team to continue posting such videos. Thank you so much.

Wow you're the best. I spent 2 hours in class and didn't get a damn thing but this 10 minute and I feel like an expert. Thanks a lot.

I’m so impressed by how effective your short videos on VSWR and S Parameters are. I’m a lecturer who hasn’t worked in the field for many years but does occasionally dabble as a hobbyist. Recently I have been called upon to teach fundamental radio communications and it’s very refreshing to see these videos. Thank you.

It's been 50 years since I first saw the Smith Chart, never got it; now I understand a lot of things in ten minutes. Thanks. K4QET

Has been 15 years I'm looking at antenna theory and never understood a Smith chart. In 10 minutes, I got it

Excellent presentation. Should be mandatory for anyone that works with or plans to work with RF.

This is THE BEST "Readers Digest" Version of Smith Charts Ever. Thanks for this AWESOME Video and "To the Point" .approach!!

God bless you mate, I have an exam today and I couldn't understand a single word from my brain-dead teacher. Thank you!

That was really well done. It was the perfect presentation style (at least for me). And there was little to no subtle marketing of your company's brand; you simply presented the base concepts along with some historical background of who the Smith in "Smith Chart" was. I understand this so much better now. Thank you.

I recently purchased a NanoVNA to tune my HF amateur radio antennas minimising the needing for a matching transformer. However, I was sticking to the VSWR display because the Smith chart looked complex. Thanks to this video I have found out so much more from reading Smith chart graphing now that I understand them! Thanks for making this understandable and clear.

Thank you very much! I have started to read about Smith charts many times but always given up before getting to grips with it. Your professional presentation lifts the mystic vale and reveals the elegant simplicity of the chart. Thank you.

Back in school, the Smith chart was clear as mud. After watching this video it is a lot clearer. Good job.

[MichaelShimniok]

Outstanding job on this video. Simple, to the point, easy to understand, and clearly presented. Bravo!

[szu-yulee]

This video should be directly used as teaching materials in university. So concise and inspiring.

Excellent. Just excellent... being a maths "dumbo" I've always struggled with the Smith Chart. Being a licensed radio amateur a proper understanding of the chart, it's functions, AND HOW THEY CAN BENEFIT ME by properly understanding them escaped me year on year, . NO MORE. Paul, Thank You ! this presentation should be part of every single radio amateurs course !
Am very very grateful to you for this more than excellent video. Your companies instruments for us radio amateurs are the stuff dreams are made off. Sadly... lottery tickets to win them are far and few between... but, ... we live in hope! <Smile>
Thank you again Paul.

This is the best explanation I have ever seen Understanding the Smith Chart. Well done!

[lowearthorbit-delio]

This is the best Smith Chart refresher/lesson i've had. It makes me think why it has to be so complicated before. The technology ( video/graphical presentation) helped . Thanks. The training materials on this site, are all so Zen like.

The Tōsaku Mizuhashi Chart was published in 1937 two years before this Philip Smith Chart!!!

This was a great refresher after barely using it for a few years. Also, I don't remember my profs teaching that it was a transformation of the cartesian representation, that definitely makes this easier to understand.

[sikandark]

A perfect way of explaining things. This guy should get an all time best-teacher award.
