Wireless functional testing of RFID tag
First Claim
Patent Images
1. A method, comprising:
- transmitting a wireless signal to a circuit die for a RFID tag, while said circuit die'"'"'s positioning is under the control of a machine that transports said circuit die, to administer a functional test to said circuit die, said circuit die having an on-die antenna adapted to receive said wireless signal.

Abstract
Wirelessly testing an RFID tag before it is packaged or otherwise entered into a process reserved for “working” RFID tags is described. Various processes that employ such wireless testing as well as various “on-die” RFID tag antenna designs for facilitating the wireless testing are also described.
