HackadayU: Introduction to Antenna Basics - Class 2

[@tomstrum6259]

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.....

[@theconspire7608]

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!

Great course! 4:52 I really like Michael Ossman's saying "be a good neighbor in the spectrum" :D

[@garycmartin]

Thanks Karen, really enjoying your Hackaday class videos.

[@vhe8221]

Great practical presentation. Thank you so much!

[@labyrinth2]

Thank you for this excellent presentation

[@Daniel-p3g8q]

NanoVNAs are fairly cheap and very powerful. Highly recommended using one of those to start with.

[@mutazshannag2137]

Many thanks Karen you lectures were both very helpful. God bless you

[@poorman-trending]

Can we get these videos updated with the links in the description please?

[@mayermetro]

Thank you for a awesome class

[@BrentandRebeccaGayman]

Presented very well, thank you!

[@tydengr]

Great class

[@mjw-li9gc]

Thank you for sharing your knowledge!

[@MrIshaqm]

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?

[@amalam2299]

could you refer to some textbook where I could find solved problems related to the antenna?

[@kavithasenthilkumar4533]

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

[@karlharvymarx2650]

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.

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.

[@RetroXpert]

Thank You!!

[@BryanGrigsby]

Awesome, thank you! On to class 3...

[@hungdo4611]

May I ask if we put 6db attenuator in series with for example 3db, would it make an equivalent 9db attenuator? Thanks.

[@iprogramplus]

hi where can i find the links discussed, thanks,

[@sotecluxan4221]

Well taught!

[@abdiwahabahmedomar2399]

awesome

[@danfitzgerald2734]

Great tutorial… right? 14:05

[@samtzam3774]

dB (decibel) is not a measuring unit but a power comparison tool.

[@SMShannon55]

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.

[@birk_lab4805]

RIGHT?!
