RF harvester in solarpanel

hi... is it possible to make the copper strips behind the solar panel as antenna ..... please rpy friends

Any conductor of any form can be used as a RF antenna. Please be aware that the "solar panel" itself is a conductive wall, so the copper strips on its back would not act as a good antenna.

Please read some antenna textbook to see how typical antennas are designed. Then you can see if your structure can or cannot be used as an antenna.

What RF frequency signal do you want to pick up with your device?

Did you plan to harvest power from RF ?

my designing frequency is 3.5GHZ...thank u i will refer
