Radio Frequency Identification (RFID) is a technology that current students will experience in their professional careers. This paper describes simple and low cost experiments to give the students a basic understanding of the working principles of this technology. The experimental activities described here do not pretend to be exhaustive in breadth or depth of knowledge, but just to give students basic hands-on experiences in RFID systems. Keywords: RFID; education; experimental; antennas; tags I. Introduction Engineering and engineering technology graduates are expected to work with new and emerging technologies through their professional careers. Faculty members in these programs should become proactive at the time of responding to today’s industry needs as well as anticipating its future trends. This will give their students critical tools to succeed in their professional careers. One of these new emerging technologies that graduates will encounter in their professional careers is Radio Frequency Identification (RFID). After its initial adoption by large retailers such as WalMart as well as the United States Department of Defense the technology is mature enough to be adopted by medium and small companies at an increasing rate (IEEE-USA, 2005).

the Technology Interface Journal/Spring 2010 Lozano-Nieto Volume 10 No. 3 ISSN# 1523-9926 http://technologyinterface.nmsu.edu/Spring10/ RFID is a technology that was developed during World War II following the invention of radar to distinguish between friend and foe aircraft as in its initial stages, radar only returned echoes of objects without the ability to make further differentiations (Stockmam, 1948). RFID uses radio frequency for communication between a tag –sometimes called a transponder-, and an interrogator –sometimes called a reader. In its most basic form of RFID, the tag transmits a unique identification number prestored in its memory when it is immersed in the electromagnetic field generated by the reader. In more advanced forms, the transponder is able to execute additional functions following the command sent by the interrogator, including rewriting the data stored in its memory. The basic structure of a RFID system consists of three basic parts:
