RFID Antenna
|
|
A type of antenna found on transponders used in conjunction with RFID (Radio Frequency Identification) systems in which the transponders are attached to a variety of goods, equipment, and documents in order to provide rapid identification, inventory management, and/or numerous security features. The antenna allows the chip to receive and relay information, such as an ID number of an individual product. Some antennas are constructed of metal and are etched or stamped from metal, such as copper. Other types of antennas are printed with digital or conventional equipment. Advances in technology are allowing printed antennas to achieve the functionality of traditional materials. Printed antennas are also less expensive. One of the most popular methods of printing antennae is with the use of silver conductive inks printed on plastics substrates or paper. Testing of RFID antennae is usually performed with ohmmeters, milliohm meters, RF network analyzers, impedance-measuring equipment, and other types of similar devices.
