RADIO COMMUNICATION DEVICE

摘要

Provided is a radio communication device which communicates corresponding to signals in a first frequency band and a second frequency band having lower frequency than the first frequency band, respectively, and comprises a flat plate object, a first integrated circuit having a communication function in the first frequency band, a first conductive object connected to one of two input/output terminals of the first integrated circuit, a conductive object group composed of a plurality of second conductive objects wherein at least one object is connected to the other input/output terminal of the first integrated circuit, a second integrated circuit having a communication function in the second integrated circuit, and a spiral shaped conductive object wherein a winding start side thereof is connected to one of two input/output terminals of the second integrated circuit, and a winding end side is connected to the other of the two input/output terminals, wherein the conductive object group and the spiral shaped conductive object are formed on opposite surfaces of the flat plate object so that more than half of the spiral shaped conductive object overlaps the conductive object group when they are perspectively viewed from the normal line direction of the flat plate object.
