Best Antenna and Rectifier Diode

[Baluncore]

To extract significant power you must tune your antenna and the coupling to the rectifier. The tuning will be frequency dependent so all your frequencies will need to be within about one percent of each other.

There is also the problem of direction. To capture significant energy you need to aim your antenna, or it's reflector. Unfortunately, multiple transmit sites will probably not be in a line and in the same frequency band.

45tt, designing an antenna is not something that everyone can do. There are so many applications, types and considerations of antenna design that only professionals can design an antenna that can actually transmit some power. There are so many different types of antenna for so many different types of frequency with so many different power output specifications. For anyone to answer this question, it is important that you mention how much gain is required as well.
