Design Your Own NFC Antenna

In this video we look at designing your own NFC antenna.
Just recently I was tasked with designing an NFC antenna for a project, the current design we had just did not match what I had in mind, so I decided to make my own and try it out!
This video covers the design process that I went through and so you can hopefully design your own too!

Very cool! Thank you

[@jordanrininger9212]

I've been a little intimidated about figuring out this part of my circuit, and your video helped a ton. Even just your tip about the free tools to design my antenna and impedance matching circuitry. Thanks soooo much!

[@romulosendoromulo]

Awesome! Thank you very much!

[@namsukkim4625]

Thank you for your video!

cool video thank you ,if I just sign a NFC antenna, how can i get its real S11 in HFSS? I tried use a capacitor to replace the chip in tag but it not work

[@raohamza4484]

Hi, Very informative tutorial. Could you please make a video on this chip, PN532, and how to design its antenna?

[@WinterCircuits]

Hi I will definetely take a look at it!

[@MarioPToledo]

hey great content! This antenna can be use for wireless charging? thank you in advance!

[@WinterCircuits]

I have seen some cases with the use case of NFC charging, for example I believe ST do a range of chips. I would believe if it was that specific you could use this for wireless charging if its NFC. In case of QI charging, it would require something different. You can get a lot of off the shelf antennas so it might be worth looking into if you need something for your project.

can i attach an antenna tht i bought online to my 13.56 mhz reader? if so, which antennas would be compatible with which models of 13.56 mhz readers?

[@WinterCircuits]

You'll be able to use an external antenna as long as its for 13.56mhz

[@popeyes7569]

@@WinterCircuits do you know approx how far the 13.56 mhz nfc reader would be able to reach with an antenna?

[@mustygreenbeanie_bass_]

Does this increase the scannable range for NFC Chips?

[@WinterCircuits]

If you mean will designing the appropriate antenna will you get further range for what NFC allows? Then yes.

Your tutorial is absolutely the best for me 😁

Might be a good video, if anyone could hear it...
