RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

how to make a passive RFID tag ? - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

Hello, I am e new member and this is my first
post .I have some question about RFID tags.Could you illuminate me?It's
the first time I work with something like that and it is possible to
write down something incorrect, so be prepared!
I have a project
on building a passive RFID tag with CMOS technology and I need some
help about the circuit design.could you propose some expectant circuit
designs or some info and soutces to look for?
What I've found
so far, is that my tag must include the following parts:
backscatter modulator, a demodulator, a voltage multiplier,a voltage
regulator and a rectifier. Do you think I need some more parts?
Can anybody experienced help me find such parts? I need a simple circuit,so
as not to be confused ,and I'll have to simulate every part of the tag
seperately on a VLSI program afterwards.
Witch technologies can
you suggest to base on?

For thew antenna part, check this URL: http://www.maxource.com/html/RFID_antennas.html.

Thanks for responding, but with a quick view at it ,I think that
this is not what I'm looking for.I want an antenna as a component of
the RFID tag,so as to design it ,not the RFID reader antenna that detects
the tags.It's so difficult to find the parts of the tag, bcause usually
they buy it and do not deal with the design of the tag circuit...The
only source I've got,is some papers of i-eee, though they are not always
