ABSTRACT:
A ground electrode is provided on a first surface of a dielectric body. A radiation electrode has a first end which is left open and a second end which is connected to the ground electrode. A feeding terminal is provided on the first surface. A feeding electrode has a first end which is connected to the feeding terminal and a second end which is connected to the ground electrode. At least a part of the feeding electrode is extended in parallel with an elongated direction of the radiation electrode, so as to excite the radiation electrode with an induction coupling in a non-contact manner.
