I am glad. When I search for that info I couldn't find any so I had to make the test and wanted to share if anyone need that info. Others helped me so I am so happy to help too.
Hi, Thank you so much for making this video. I want to embed an RFID antenna into a 3D printed disk and wanted to find out how to design a suitable antenna. This video told me everything I needed to know. I need to make a circular 88mm diameter antenna. I plan to use 0.5mm wire so estimate around 47 turns at a guess from your results. I will try from 50 turns down in 5 turn steps. does this sound reasonable to you? Many thanks again for publishing your work.
The best way to get max distance is to make a test like I did, only difference is that you have starting point. I guess that it would be best that you start from 50t and test, and reduce it one by one turn and test every time. It might be perfect at 45t but I suggest you try 49 48 47 46 45 44 43 turns and test all of them. When you find perfect number of turns you make new antenna with those specs. That is how I would do it. Maybe you can get away if you make 45t and be done but you would never be sure if one more or one less turn be better. I am glad to be of help that is why I made this.
Thank you so much
Thank you so much sir, you help me a lot! Congratulations!

Thank you so much, please make a video for the em4100 / tk4100 rfid reader, with an antenna radius of 6.5CM how many times should the coil be wound
Go to 23.40 and use this parameters. 0.5mm wire / 50-55 Turns / 6.5cm radius (65mm) / 125khz rfid
@@YugoZex thank, i will try
