ITTC Project

Evaluation of RFID Tags on Metal Cylinders

Project Award Date: 09-13-2007

Description

One of the missions of the University of Kansas is to disseminate knowledge. With experience in solving the near-metal problem, ITTC/KU is well suited to partner with companies to transition this knowledge.

ITTC researchers have performed detailed simulations that showed the tag-on-pallet performance of a single tag. The new effort will seek to understand the tag performance of multiple tags, especially when two tags are relatively close to each other. If two tags share the same space, they tend to couple: i.e., the two antennas tend to act as a single antenna. In some cases this is beneficial, but in others, problematic. This task will seek to better understand the tag-tag interaction with multiple tags on a pallet and in different configurations.

Other observed concerns involve the reduced performance of corner cylinders when the tag is facing outwards, mixed pallets (large and small), and different stacking (4-5-4-5 vs. 4-4-4-4).
