How to extract L, C for microstrip antenna in HFSS V10?

I wan to find the lumped circuit model for any microstrip antenna using HFSS v10. Any suggestions would be appreciated.

I have the same problem

can anyone post the aanswer for this. thanks in advance

In general, you will not find good methods to get lumped element approximations to antennae. Lumped element approximations are good for objects less than about a tenth of wavelength, and most antennae are at least 0.5 wavelengths.

For HFSS, you can try the "low bandwidth" option of the "Equivalent Circuit Export" in the "Matrix Data" panel (right click on a solved Setup to get this option). It may work.

If that doesn't work, this thread has some useful info: https://www.edaboard.com/viewtopic.php?t=218840
