摘要： A resonant antenna circuit for a radio frequency identification (RFID) reader generates an electrical signal for activating a passive identification tag. The identification tag in turn generates a coded electrical signal that is detected by the reader. The electrical characteristics of the resonant circuit are actively and dynamically altered so that the antenna performs more optimally during the transmit and receive intervals.

In many embodiments, the system includes a portable RFID reader and one or more stationary antenna assemblies. The stationary antenna assemblies typically include a loop antenna in a first location and a ferrite antenna in a second location. EID tags in the reading zone of the loop antenna can be read using the portable RFID reader via an inductive coupling between the resonant antenna in the portable RFID reader and the ferrite antenna in the stationary antenna assembly. One embodiment of the invention includes a portable reader having reader circuitry configured to generate an activation signal, a first resonant antenna, where the first resonant antenna is electrically connected to the reader circuitry, a reader housing containing the reader circuitry and the first resonant antenna, and a stationary antenna assembly having a resonant antenna unit including a housing and a second resonant antenna, a loop antenna unit including a housing and a loop antenna and an electrical connection between the resonant antenna unit and the loop antenna unit. In addition, the first resonant antenna in the portable reader is inductively coupled to the second resonant antenna in the stationary antenna assembly.

摘要： In an inductively coupled radio frequency identification (RFID) system deployed in animal and livestock applications, reading system efficacy can be compromised by animal movement on, around, or near metal structures prone to producing sonic frequencies. Such is the case, for example, when a walk-by antenna is mounted at the entry door of a livestock transport trader, and animals transit on a metallic ramp and metallic trader floor. Associated with the observable acoustic noise are subtle disturbances in the magnetic field surrounding the antenna due to vibrating metal altering the reluctance of the antenna's magnetic field. This acoustic noise manifests itself as an electrical noise phenomenon that interferes with the signals of certain types of identification tags which rely on amplitude modulation. The detrimental effects of acoustic noise from metal structures can be mitigated by using a multi-loop antenna that limits the spatial distribution of the transmitted magnetic field and cancels close by magnetic field disturbances.
