I am getting 0.01 V from a source And I wanna strengthen the signal
so If I give that same signal to multiple bridge rectifiers... Can I get the Output
with good strength? i.e., Vout= 2V or something else...
Please clarify this doubt...
Thank you...
 

I presume you are trying something like RF energy harvesting or a passive RFID tag.

We would normally expect that the rectifier circuit is impedance matched to the RF source (receiver antenna or coil). In this case multiple rectifiers can't increase the output voltage.
 
I wanna do a project called "Wireless Mobile Charger" which requires no power supply... So, can u give me any suggestions... i.e., about antenna, circuit etc.,
Awaiting your reply
 

What's the available field strength and respective antenna output power according to your estimation?
 

Sorry, but the "Windshield Mount Electronic Antenna for Car FM Radio" isn't related to energy harvesting. It even needs a power supply to give the intended output.

Generally speaking, there have been several edaboard threads about energy harvesting based on erroneous belief. I can't yet recognize a realistic idea behind your posts.
 

Then Is there any antenna with high gain, small in size, and requires no power supply???
 

If you were to make a traditional 'crystal' radio set (which needs no power supply)...

and you are near a transmitting tower...

it is a classic trick to draw electrical energy from the broadcast radio waves.
