Abstract: A conductor strip spiral antenna for an RFID tag is provided to freely adjust impedances of a terminal and the conductor strip spiral antenna by varying parameters of the antenna. A conductor strip spiral antenna is connected to a tag chip of an RFID(Radio Frequency IDentification) tag and includes a pair of first conductor spirals(20,20') and a pair of second conductor spirals(30,30'). The first conductor spirals are commonly connected to one terminal of the RFID tag chip and arranged to face each other in a horizontal direction. The second conductor spirals are commonly connected to the other terminal of the RFID tag chip and arranged to face each other in a horizontal direction. The first conductor spirals and the second conductor spirals are arranged on upper and lower portions of the RFID tag chip, such that they are vertically symmetrical with respect to the RFID tag chip.
