Abstract
A non-feeding element is provided with a proximity-providing gap from a feeding element that receives RF power from a feeding point on a circuit board, and a resonant state is generated there by capacitive coupling. The non-feeding element is formed so as to resonate at a frequency different from a resonant frequency of the feeding element. The feeding element and the non-feeding element have alongside-ground-terminal extending portions formed so as to be spaced from an edge surface (a ground terminal) at one end of a ground surface formed on the circuit board and to extend in a direction along the edge surface at the one end of the ground surface. At least one of the feeding element and the non-feeding element is formed three-dimensionally with a plurality of bending portions so that at least parts of the alongside-ground-terminal extending portion of the feeding element and the ground-terminal extending portion of the non-feeding element have substantially the same amount of spacing from the ground surface, with a mutual gap in a thickness direction of the circuit board.
