[IE3D] About using a frquency-varied termination impedance ?

hello.

Now i am designing a tag antenna in IE3D.

I want to match the my tag antenna with a commercial tag chip.

(In reality) as the frequency changes, the impedance of tag chip is changed.

But in my limited knowledge about IE3D, i can use only a constant number as the termination impedance value.

Is there a way to use the frequency-varied chip-impednce as termination impedance in IE3D?

p.s. i attached the paper which showed such results.

Hi, Insang:

On IE3D, you can use MODUA to do mixed EM and circuit simulations (or EM and Circuit Co-Simulation). If you have a frequency dependent load, you can write it into a .s1p file. Then, you can connect it to the IE3D geometry or s-parameters on MODUA.

Best regards,
