Radio IC device and radio communication terminal

摘要

A radio IC device includes a radio IC element arranged to process a high-frequency signal, a substrate on which the radio IC element is mounted, a planar conductor arranged on a first surface of the substrate, and a first wiring electrode and a second wiring electrode including respective first ends connected to a pair of input/output electrodes of the radio IC element. The first wiring electrode and the second wiring electrode are arranged on a second surface of the substrate, the second surface being parallel or substantially parallel to the first surface and including respective second ends electrically connected to the planar conductor, and defining loops when looking at the substrate from X-, Y- and Z-directions orthogonal to one another.
