Finding input and/or output impedance to do matching in ADS

[JTK93]

Hi,

i'm trying to redesign a matching circuit for this rectifier circuit with my antenna included

anyone know what tool i can use that can give me the ZIN & ZOUT so i can make the matching circuit ?

Regards

Small Signal Impedance will not work for your purpose because your circuit uses large signals.
Look at Impedance Definitions e.g.
Z=V/I
Connect a Current Meter and define a Voltage Node then do a HB analysis and find this impedance.
