[Noisebridge-discuss] seeking donation of RFID reader equipment

[Jake]

as i've said several times, in the datasheet here:

page 7, shows that the chip (the tiny square in the middle) is connected 
to two large flat metal conductors on either side, which will function as 
antennas.  They are 3mm by 3mm each.  A dipole.

if you were truly a CIO of a wireless company you would understand that 
that will work as an antenna.  a dipole antenna.

keep in mind we are trying to achieve a very small region of coverage,
instead of just detecting these things anytime they are in the mission.

We want them to only be detected when they are near the door or the 
elevator, whereas their normal performance is on the order of 5 to 20 
meters.

if you want higher range, you are welcome to stick them onto larger pieces 
of metal so they can be detected from across the street.
