  1. Thanks alot even im doing project on design and simulation on printed antenna for nfc plz help me i beg u

  2. So, where is the calculate button?

  3. Thank You for your calculator!

  4. Thank you for this calculator. It’s the closest one that I’ve found for my needs. I am however going to be using a 38awg round wire for my application. :( Is there another calculator that you know of that will calculate the inductance of my antenna setup?

  5. How do you measure thickness in oz. Thickness is usually either in micrometer or millimeter, right?
