RF Energy Harvesting Simulation

Click For Summary
The discussion focuses on simulating RF energy harvesting to measure power conversion efficiency, specifically in the 2.4 GHz band. Participants emphasize the importance of defining the simulation parameters, including the physical size of the device and antenna configuration. They suggest that the simulation software should be chosen based on the specific scenario and energy sources available. Additionally, there is a call for more detailed information about the energy levels and harvesting conditions to provide better guidance. Overall, the conversation highlights the need for specificity in simulation requests to achieve meaningful results.

I want to do RF energy harvesting simulation for the measurement of Power Conversion Efficiency.
So how can be simulation done on a single platform?. Kindly suggest

Welcome to PF. :smile:

Can you say more about what you want to simulate? What types of simulation software do you have access to? SPICE, COMSOL, NEC (antenna simulations), others?

What frequency band(s) do you want to harvest energy from? What is the physical size of your device and what is your planned antenna configuration? Do you have information about what field strengths are available in the areas where you want to do this RF energy harvesting?

I want to use the 2.4 GHz band and the entire thing I want to do in simulation. I want to increase the power conversion efficiency. So which is a platform where I can do this
 
@berkeman asked you five questions. You answered one. If you answer the other four, you'll get better advice.

Exactly. A simulation package cannot define your problem; it can only work out results from a scenario you specify. The only 'simulation' that can exactly do your job would have to be one that was written by someone else who posed the self same question. Perhaps what the OP should be doing, to start with, is to estimate the level of energy that is wasted the then estimate the fraction of that energy that the 'harvesting' process could grab.

I always get grumpy about questions about Harvesting unless they are very specific. Say where you feel there is some 'spare energy' to be had from an existing process. If there is some spare energy then I would suggest that someone has not got an efficient design in the first place.

Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
