Hello,

I have application with similar construction to RFID, however I'm not sure if my calculations are correct. This is crucial for my project because it's supose to by my power supply.
I'm trying to calculate what voltage and current would be inducted in rectangle antenna by magnetic flux at specific frequency. I found out that:

Code:
U = - N * d(Mflux)/dt
where: Mflux - magnetic flux, N - number of wraps in coil (1 in my case)

so if magnetic flux is sine at specific frequency than inducted voltage would be also sine at same frequency. If I want to calculate peak-to-peak voltage can I divide peak-to-peak magnetic flux by half of period of sine wave?

Also this is eqution that I've found for calculating current in antenna (coil):

Code:
I = N* Mflux/L
where: L - antenna inductance (page 14 from file below).

This is the file that I used for calculation: https://application-notes.digchip.com/022/22-18922.pdf

Thank you for any help.
