Abstract
Multiple RFID integrated circuit microradio chips are located at the feed point of an RFID tag antenna for greater, reliability, elimination of testing and to take advantage of coherent microradio operation for increased gain and power, better signal-to-noise ratios, improved range and low bit error rates.
Claims18
In an RFID tag system, a tag having at least two integrated circuits.
A method for establishing robust communication between an RFID reader having a transmit antenna and an RFID tag having a receive antenna including a feed point, comprising the step of providing a number of RFID integrated circuit microradio chips at the feed point of said antenna such that at least two of the RFID microradio chips are effectively coupled to the antenna.
A testless system for providing an RFID tag in an RFID system, including an RFID reader and a tag, comprising the steps of:
- providing the RFID tag with an antenna having a feed point;
- and,
- depositing multiple RFID integrated circuit microradio chips at the feed point of said antenna, whereby there will be enough operational RFID integrated circuit microradio chips properly coupled to the feed point of the antenna that individual testing of either an RFID integrated circuit microradio chip or its coupling to the feed point of said antenna is unnecessary.
In an RFID tag system in which a tag has an antenna with a feed point, a method for improving the performance of the system comprising the step of providing multiple RFID integrated circuit microradio chips at the feed point of the antenna.
In an RFID tag system a tag having at, least two integrated circuit microradios tuned to different frequencies.
