Power harvesting (RF)

[eng.asi]

Hi all
I work on RF power harvesting
I tried the hardware and found that the circuits works at different frequency
the simulation works at 900 MHZ but the hardware at 720 MHZ with the same efficiency
Any comments ?

What you mean under "simulation works" ?

900MHz is one of GSM frequency.



Best regards,

Apparently your hardware was designed to operate over a wider band. Simulations and the real world often differ a lot if you have not noticed. Keep it in mind when you try again.
