Please help me if anyone knows if the s parameters (s11 especially) we measure in ADS for the rf energy harvesting rectifier circuit is the same as the actual measurement of s11 on network analyser at the input port sma connector in the fabricated circuit ?

Please help thanks in advance :)

It is not measurement. It is EDA Tool Play.
How do you evaluate S-parameter in EDA Tool Play ?
Small Signal S-Parameter based on SP Analysis ?
Large Signal S-parameter based on HB Analysis ?
Small Signal S-Parameter based on HB-SS Analysis

What power do you apply as stimulus ?

If your EDA Tool Play can reflect stimulus power, PCB, SMA, etc in actual measurement properly, you can expect good match result with actual measurement from EDA Tool Play.

No power is applied, just for testing purpose of the rectifier circuit. (or shouldn't we test the s11 of only the rectifier ckt?)
 

Thanks for the answer and info. Because when I simulate it in ads I get 2 ghz resonant frequency , but when I measure it using network analyser I get the resonance at 4 ghz and a very suppressed resonance >-10 db at 2 ghz

Simply simulation model can not reflect actual situations such as pattern of PCB, IC package, etc.

I think 4GHz is a parasitic resonance which masks 2GHz resonance.
 

Is there any way I can find out what is wrong with the fabricated circuit or a way I can make it useful for the same purpose of 2 ghz signal rf energy harvesting ?
