I'm trying to simulate an antenna and matching unit, which has a capacitor in it. The capacitor is physically much smaller than the wavelength.

It is possible to do this in HFSS? I guess it would be possible to draw two parallel places, with a dielectric, which have the capacitance required, but is there a better way?

If I did draw two plates, would it be most sensible to use a vacuum dielectric so the sizes are not too small, or would I be best to use a high dielectric material?
 

Hello Debora

the way i know of using passive elements in HFSS is to draw a plate where you would want to place the capacitor and then assign it a RLC boundary with the associated values of it. HFSS will simulate the structure accordingly.

Click to expand...

Did you ever get a cap incorporated into your model?

I am faced with a similar situation at the present ...
