Manufacturing Technique for Passive RFID Tags with Shorted Microstrip Antennas

University of Kansas
posted on 01/12/2006

"A microstrip RFID tag is comprised of an antenna, matching circuit, integrated circuit (IC), substrate, and ground plane. For low manufacturing cost, the antenna, matching circuit, and IC are all on the same plane. The ground plane is separated by the substrate. Using a microstrip antenna, one can construct an RFID tag that works on otherwise difficult-to-tag materials such as metal or water."

Suggested Uses

In manufacturing inexpensive shorted microstrip antennas. The application for shorted microstip antennas is in application where tags 1 by 3.5 inches are too large, such as tagging tools, small electronic devices, medical tools, etc.
