I am building a rectenna system to convert the strayed energy at ~2.45GHz into DC.
I build a equiangular spiral antenna and connect a schottky diode to it.Building the antenna, I printed the equiangular spiral shape on the PCB and etched it. I found that even if I remove the antenna, the diode itself can pickup signal.
any advice on whats wrong with my antenna?
