Hello,

I am investigating some rectenna topologies to my final course assignment, and now i have a problem with this topologie (Shunt Diode), the problem is: I dont have any rectification, Vin is equal to Vout... What i am doing wrong?

Thanks

Make it large impedance at your RF operating frequency, so that it blocks RF and only passes the DC.

Hi, i've made your suggestion, but i think something is still wrong, because i read in some papers that the efficiency of these topology is better than the series configuration.

The efficiency of this configuration is something about 32%

And of this one is around 17.5 %
