Abstract
A first radiation electrode is formed on a bottom surface of a no-ground conductor formation area of a board, and second radiation electrodes are formed on a top surface of the no-ground conductor formation area. A longitudinal electrode of the first radiation electrode is electrically continuous with a ground conductor. A first end portion and a second end portion of a transverse electrode of the first radiation electrode extend toward the ground conductor. The transverse electrode of the first radiation electrode operates as a radiation element for radiating a signal at a first frequency. The second radiation electrodes each operate as a radiation element for radiating a signal at a second frequency, and also as a capacitive feed electrode for the first radiation electrode. This enables to strengthen directivity toward an antenna portion side (forward direction) of the board, and further enables multiband use.
