how can i draw an equivalent circuit model of patch antenna(RLC) in ADS

hi all
help me in solving this
how to draw an equivalent circuit model of patch antenna(RLC) in ADS
can u tell step wise process from any example in ads

Some programs can extract RLC values from s-parameters.
For instance Sonnet can extract RLCM values from simulated s-parameters for Inductors.ADS has some capabilities (Broadband/Narrowband SPICE modelling utility) but they are limited.
Whay don't you use simulated/measured s-parameters in a black-box in your simulations ?

can u tell me more about using imulated/measured s-parameters in a black-box in my simulations
and how can i derive rLC components from my planar microstrip antenna (CPW fed)
reply soon
