Field distributions and RFID reading within metallic roll cages

The performance of RFID tag reading is assessed within roll cages. The insertion loss of a cage side is simulated along with the field distribution within a complete cage and read measurements are taken and mapped for a horizontal plane inside a physical cage. Frequency diversity for multi-frequency...

Zusammenfassung:	The performance of RFID tag reading is assessed within roll cages. The insertion loss of a cage side is simulated along with the field distribution within a complete cage and read measurements are taken and mapped for a horizontal plane inside a physical cage. Frequency diversity for multi-frequency tags is proposed as a method of reading within standing wave nulls.
