Development of all-organic antenna printed for passive UHF RFID application

The purpose of this paper is to present a flexible conductive polymer antenna for passive UHF RFID using the inkjet printing technology. This all-organic antenna was used to assembly a RFID tag using the Alien Technology IC for UHF application in a strap package. Simulations were performed using the simulation software CST and their results were compared with the measurements, which were performed using an UHF TEM Cell and an UHF RFID reader. This article shows that the all-organic antenna can be functional and can be read by a UHF RFID Reader available on the market. These conductive polymer antennas are compared to antennas with the same design manufactured using a FR-4 and Copper.
