Disclosed is a multiple loop antenna for a radio frequency identification (RFID) reader, and more particularly, to a multiple loop antenna for a RFID reader that reads information stored in a RFID tag or inputs new information to the RFID tag by inductive coupling.;The multiple loop antenna for a RFID reader serves to communicate information with the RFID tag by inductive coupling, and includes at least three winding groups where they have at least one turn for each group. The winding groups are connected to one another in series and in parallel.;And the same structure is also applicable to RFID tag antenna.
