1. A wireless communication device comprising:
- a first radiating element and a second radiating element, which define and function as a dipole antenna;
a feeder circuit including first and second input/output electrodes, the first input/output electrode being connected with the first radiating element, and the second input/output electrode being connected with the second radiating element; and
a first substrate that is provided with the feeder circuit;
whereinthe first radiating element is provided on a first surface on or in the first substrate;
the second radiating element is provided on a second surface on or in a second substrate which is separate and distinct from the first substrate;
the first surface and the second surface are different surfaces from one another; and
a communication path between the first input/output electrode and the first radiating element is different from a communication path between the second input/output electrode and the second radiating element.

Abstract
A compact wireless communication includes a first radiating element and a second radiating element, which define and function as a dipole antenna, a feeder circuit including a wireless IC chip coupled with the first and second radiating elements, and a feeder substrate that is provided with the wireless IC chip. The first radiating element is provided to the feeder substrate. The second radiating element is provided to a substrate other than the feeder substrate.
