<p><P>PROBLEM TO BE SOLVED: To obtain a radio communication device provided with an RFID tag function to be shared by an LF band or HF band RFID system having the same communication range as an LF band or an HF band, and an UHF band, and a UHF band RFID system, by securing the largest possible area for mounting each of the antenna antennas with respect to the LF band or HF band, and the UHF band. <P>SOLUTION: The radio communication device includes: a rectangular coil antenna formed on one principal plane of a dielectric having the one principal plane and the other principal plane, and having an IC chip for coil antenna electrically connected; a monopole antenna formed on the one principal plane or the other principal plane of the dielectric at an outer periphery of a winding constituting the coil antenna and grounded by the coil antenna; an IC chip for monopole antenna for receiving power supplied from the monopole antenna; and a winding bent part which is a portion of the winding constituting the coil antenna and in which the winding constituting the coil antenna is bent to an inner periphery side. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
