Passive RF battery? Answered

Hey i was just wondering what are typical conversion rates for signal to electricity in passive RFID tags?
Information on the subject is usually not geared towards the electrical charge being generated.

Ehh... that paper kinda underscores allot of the issues i'm having; It's main concern is not passive tag circuit design at all. It's more of a cost benefit analysis, which isn't useful for me really.

That said, that paper is kinda skewed. A simple Google search for the price of different RFid tags will quickly show the differences in price. Passive tags beat non-passive tags in price on an order of magnitude (a penny versus a dollar), so unless their paper brings different applications into consideration, They've failed before they've started.

I guess the economics of producing a powered RFID tag will always be more expensive than the simple passive RFID tag. I am not an EE nor a purchasing agent so I don't know about researching the components and manufacturing costs of each. You might have to look up antenna design papers to figure out the efficiency of each detection method. Is this research for a thesis or were you tasked at work to develop a product?

Neither. It's personal interest in the subject.
People demonize RFid tags, but there's allot of positive things that could come of them.
I will have to look into antenna design papers i think.
Thank you for your help.
