Dear alll

I'm just a newbie in HFSS designing.

I want to fnd out the characteristic of passive element using HFSS
(for example Y11 phase, Y11 magnitude, capacitance, inductance)

I made a capacitor using LTCC process and then I simulate that using HFSS.

But the measured data differ from the simulation result. I am uploading the file

I designed. please tell what is wrong with it.


thank you for your help.

I did have a look at your design, didn't simulate it, though.
Try to have a higher air box. Usually for radiating structure, the airbox should be at least 1/4 lambda (of the lowest freq) away. In your case, it does not need to be that high.
