Design a magnetic based coil using FEKO

Question

Hi

Good day,

 

I would like to start with creating two different magnetic based coils as Transmitting coil (TC) and Receiving coil (RC), to measure the Z impedance values changes with respect to the movement of TC around RC.

Following are the configuration which I would like to proceed,

 

Transmitting Coil:

L

67 uH

Q

22

Ccalc

24.19 nf

-

-

F

125khz



Receiving Coil:

Coil Configuration

L

728.73 uH

Q

53.24

R

15kohm

Ccalc

2.224nf

F

125khz

The Receiving Coil (RC) resonated at a frequency of 125kHz and diameter of 7cm. Transmitting coil (TC) dimension is 9 x 9 x 9 mm^3.

Datasheet of RC as: https://www.rfsolutions.co.uk/downloads/1457021091DS-ANT-125K.pdf

Initially, the RC and TC will be 3cm away from each other on z axis. The Impedance( |Z| )  value can be measured with respect to the movement of TC on x-axis/y-axis.

-> The RC: loop antenna actual dimension, the copper wire diameter, number of turn, the diameter. (the details of the coil determine the inductance value)

For RC:
0.236mm diameter (34 swg) Enamelled Cu wire.
Diameter Antenna: 7cm internal ,
Number of turns: 67 turns
Inductance: 700uH
Quality Factor (Q): 17


For TC:
Inductance: 67 uH
Quality Factor (Q): 22
Capacitor: 24.19 nf
Frequency (F)    125 kHz
Number of turns: 52
Diameter: 8mm



-> Matching circuit details.

Matching circuit For RC : C = 2.3159nF  (Formula:F=1/2π √LC)
Matching circuit For TC : C= 24.19nF    (Formula:F=1/2π √LC)

 

kindly can you suggest me the step or user manual for me to start on to this project.

 

Looking forward to hearing your comments on it,

Regards
