RF-Energy Harvester Optimization

[migi07]

Hello,

i’m trying to create an impedance match for an RF rectifier at 0.868 and 2.44 GHz.

In the first step, I adapted the simulation so that the simulation and measurement match.

In the second step, I calculated the T-section impedance matching.

In the third step, I inserted the calculated values in Qucsstudio, simulated and tuned them.

I would like to get better results with the optimization simulation.My problem is that the simulation only ever adjusts one of the two frequencies.

My equations(goals):
pass1 = min(range(S[1,1], 1.885 Ghz, 1.995 GHz))
pass2 = min(range(S[1,1], 2.40 Ghz, 2.45 GHz))
both with weight 1 and minimize

Optimization settings:
Method: grid search
Number of restarts: 1

Variables:
lengths and widths of all lines in the T-section matching network

 

I hope one of you has a tip for me.

best regards

Miguel
