<P>PROBLEM TO BE SOLVED: To provide a radio communication device with an RFID tag function, capable of securing the mounting area of each antenna of an LF band or an HF band and a UHF band as large as possible, and being shared by an LF band or HF band RFID system and a UHF band RFID system having a communication distance equal to a communication distance of each device of the LF band or the HF band and the UHF band. <P>SOLUTION: The radio communication device includes a dielectric having one main surface and the other main surface, a coil antenna which is formed on one main surface of the dielectric and to which an IC chip for the coil antenna is connected, a monopole antenna formed on one main surface or the other main surface of the dielectric at the outer periphery of winding configuring the coil antenna and grounded by the coil antenna, an IC chip for the monopole antenna to which power is supplied by the monopole antenna, and a parasitic element pattern formed on one main surface or the other main surface of the dielectric which is a surface opposite to the surface where the monopole antenna is formed and grounded by the coil antenna. <P>COPYRIGHT: (C)2011,JPO&INPIT |
