System for identifying, localizing and storing histology cassettes and slides

A system for storing, identifying and localizing supports for tissue samples embedded in paraffin, comprising

• a plurality of supports, of which each one is provided with a respective RFID tag, said supports being each
• a histology cassette (20) configured to contain a tissue sample embedded in paraffin, or a slide;
• a plurality of trays,
• of which each tray is provided with a respective RFID tag, and is configured to contain a plurality of said supports,
• each tray being provided with a plurality of seats, each seat being configured to receive a respective support and each support being adapted to be arranged in a respective seat;
• at least one component provided with a plurality of RFID antennas,
• said plurality of RFID antennas comprising an RFID antenna for reading the RFID tag of a tray of said plurality of trays, and RFID antennas for reading the RFID tags of the supports;
• at least one RFID interrogator;
• characterized in that the system further comprises
• one or more demultiplexers, by means of which the RFID interrogator can be connected to each RFID antenna of said plurality of RFID antennas, said one or more demultiplexers being configured to sequentially activate a unique signal transmission line for each RFID antenna of said plurality of RFID antennas;
• an electronic control unit, configured to synchronize said one or more demultiplexers and said at least one RFID interrogator with one another, to sequentially read the RFID tags of the supports and the RFID tag of a tray of said plurality of trays by means of one RFID antenna at a time of said plurality of RFID antennas;
• in that the antennas for reading the RFID tags of the supports which are connected to a respective output of a same demultiplexer of said one or more demultiplexers have the same and unique impedance matching network;
• wherein said impedance matching network comprises or consists of one or more resistors and one or more capacitors;
• in that said impedance matching network is arranged between the RFID interrogator and the input of said same demultiplexer;
• and in that said same demultiplexer is connected downstream of said impedance matching network and upstream of the antennas connected to the outputs thereof.
