The present invention relates to the identification of RFID devices that are arranged closely together and placed on shelving for logistical and storage purposes. Furthermore, the aspects of the present invention relate to an arrangement and/or layout of antenna coils for example in an interrogator. There is disclosed a RFID interrogator and/or method of interrogating comprising an antenna, when activated, being adapted to radiate an interrogation signal in a first area, means adapted to shift the antenna within a second area, the second area being larger than the first area. The antenna may be mechanically moveable.

Antenna design and interrogator system

The present invention relates to the identification of RFID devices that are arranged closely together and placed on shelving for logistical and storage purposes. Furthermore, the aspects of the present invention relate to an arrangement and/or layout of antenna coils for example in an interrogator. There is disclosed a RFID interrogator and/or method of interrogating comprising, in one form, an RFID docking station consisting of a stationary RFID interrogator with RFID shelving antennas and mobile cabinets with shelves where the docking station antennas and the cabinet shelves interpenetrate when the mobile cabinet is offered up to the docking station such that the antennas are able to identify tagged items on the cabinet shelves. In another form, an RFID docking station consisting of a mobile RFID interrogator with RFID shelving antennas and stationary cabinets with shelves where the docking station antennas and the cabinet shelves interpenetrate when the docking station is offered up to the shelving such that the antennas are able to identify tagged items on the cabinet shelves.
