Abstract: In an antenna for an RFID device, a feed coil is coupled to a first booster coil and a second booster coil through an electromagnetic field. In the feed coil, a first region and a second region are disposed so as to overlap with the first booster coil and the second booster coil, respectively. The first region of the feed coil is coupled to the first booster coil through an electromagnetic field, and the second region of the feed coil is coupled to the second booster coil through an electromagnetic field. Accordingly, the antenna has a high degree of coupling between the feed coil and a booster antenna and superior transmission efficiency of an RF signal, and prevents the occurrence of a null point.
