Abstract:
1. A radio communication device comprising: a radio frequency IC configured to process a radio signal; a feeding circuit connected to the radio frequency IC and including a loop electrode including a coil pattern with a predetermined winding width; and an antenna pattern magnetically coupled to the loop electrode; wherein the feeding circuit is arranged so that, in plan view as seen from a coil axis direction of the coil pattern, a first region of the loop electrode in which the coil pattern extends in a first direction overlaps the antenna pattern and a second region of the loop electrode in which the coil pattern extends in a second direction opposite to the first direction does not overlap the antenna pattern; the first direction and a line length direction of the antenna pattern are the same or substantially the same; and no radio frequency IC is directly connected or coupled to the antenna pattern.
