Simulation low frequency ferrite core recieving antenna

Click For Summary

Discussion Overview

The discussion centers around simulating a low frequency ferrite core receiving antenna, specifically at a frequency of 100 kHz. Participants explore software options and modeling techniques to calculate gain and radiation patterns.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks recommendations for software or methods to simulate a low frequency ferrite core receiving antenna.
  • Another participant requests additional details regarding the frequency band and the specific simulation requirements, suggesting that the antenna pattern could be modeled as a simple dipole.
  • A participant specifies the frequency as 100 kHz and expresses difficulty in obtaining a correct figure-8 pattern using CST EM Studio.
  • There is a suggestion that modeling a multi-turn coil with a ferrite rod core may be challenging with finite element methods (FEM), and that simpler models might yield better results.
  • One participant proposes modeling a single turn around the middle of the ferrite rod to achieve the desired radiation pattern.
  • A later reply encourages sharing the model and results if the initial attempts do not yield satisfactory outcomes.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best modeling approach or software to use, indicating that multiple competing views remain regarding the simulation techniques and expected outcomes.

Contextual Notes

Limitations include potential challenges in accurately modeling the ferrite core and the dependency on the chosen simulation method. There are unresolved aspects regarding the specific modeling techniques and configurations that may affect the results.

Hi everybody
i want to simulate, low frequency ferrite core receiving antenna . but i can't find a good and complete software or method to do this.
what is your suggestion or experience?
thanks for your attention.

Welcome to PF.

We need more details to give better advice.
What frequency band will you cover?

What simulation do you require? Antenna pattern or electrical interface?

The antenna pattern will be a simple dipole.
You can model the ferrite rod as an inductor or a transformer with inductance.
 
thank you.
frequency=100khz
i want to calculate Gain and pattern and i try to do this with CST EM studio. but it can'nt give me a correct figure-8 pattern.
 
The modelling of a multi-turn coil with a ferrite rod core will be difficult with FEM. Some things are better approximated by simpler models.

The radiation pattern will be a figure 8 just like a small loop.
I would suggest you try to model a single turn about the middle of the ferrite rod.

If you cannot get that to work, post the model and poor result as attachments to a post.
