ANTENNA FOR RADIO FREQUENCY INDENTIFICAITON RFID TAGS

摘要

An antenna for a radio frequency identification RFID(Radio Frequency IDentification) tag is provided to increase a bandwidth by forming complex conjugation for impedance match between the RFID tag antenna and a chip. An antenna(12) for a radio frequency identification RFID tag includes a first antenna element(12-1) and a second antenna element(12-2). The first antenna element includes a first conductive path, a second conductive path, and a third conductive path. The first conductive path extends between a C node and a D node. The second conductive path extends from the C node to the A node and reaches a G node. The third conductive path extends from the C node to the B node and reaches an H node.
