Rectenna S11 Parameters

Hi, i'm doing a rectenna design and i want to extract the reflection coefficient.

I've made the matching impedance using a smith chart, just like this

So, i used the s-parameters simulation, and i had this :

Why?

So, i've made another cell with just the S-parameters simulator controller, now i have this

But if i take the value of rectifier impedance and simplify the circuit (just a resitor in series with a capacitor) i have another result

So, my question, which one is correct?


Thanks

What are you doing? S11 in dBm? Values > 0dB?

That's the point, i'm totally new on RF design so i'm a little lost in all this stuff, i'm reading some articles yet... I have all these graphs in dB too...

Hi Dr.Volker Why i have different results, the harmonic balance controller influences the result?

This is the config with the smith chart tool, and S11 in dB

And this is the config. with just the S-parameters controller

Which one is the correct?

Please follow the Tutorials of ADS and Review your RF knowledge..Make them strong enough before jumping into ADS ..
I know you're newbie but you just jumped into simulator without any RF background..( you don't know even s-parameters, what they are, what they are used for..)
Please do it and come back..

Yes, you are right... I'm reading some papers and i bought a book, but i'm a little confused yet... But can you help me with this simulation issue? Am i doing the simulation incorrectly?

Thanks

One of your schematics is configured for 1GHz steps, so you miss the narrow resonances.
