Simulation low frequency ferrite core recieving antenna

AI Thread Summary
The discussion focuses on simulating a low-frequency ferrite core receiving antenna, specifically at 100 kHz. The user seeks software recommendations and methods for accurate modeling, particularly for calculating gain and radiation patterns. Suggestions include using CST EM Studio, though challenges with achieving a correct figure-8 pattern are noted. It is recommended to model a single turn around the ferrite rod for better results, as multi-turn coil modeling can be complex with finite element methods. Participants encourage sharing the model and results for further assistance.

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.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
