Monitoring antenna system |
| abstract |
A monitoring system incorporates antennas that transmit signals at predetermined frequencies; the transmitted signals are received by tags located in the active monitoring area of the antenna which then transmit signals back to the antenna. The antennas are tuned to each desired frequency prior to driving the antennas to transmit at the desired frequency. The system transmits a range of frequencies in a sequence that us es overlapping frequency steps and incorporates an antenna system that employs digitally controlled, differentially driven, scanning transceivers, and walk through magnetic induction antennas positionable in various configurations to maximize detection of tags being transported through the antenna system. A carrier may be used to transport several frequency identification devices. The carrier includes at least one circuit having an antenna and a series capacitor for tuning the antenna. Enhanced interrogatio n and communication operations are provided when the tag carrying devices are plac ed in the carrier as the energy received in a first carrier pattern is re-radiated in a second pattern to improve transceiver communication without collision. |
