Abstract
An antenna devicehas a capacitive coupling elementmounted on a printed circuit board. Strip patternstoare provided in a grand clearance regionA defined on one principal surface of the printed circuit board. The strip patternis connected to a feeding lineafter extending in a first direction from the connecting point with the capacitive coupling element. The strip patternis connected to a feeding lineafter extending in a second direction, that is an opposite to the first direction, from the connecting point. The strip patternis connected to a ground patternafter extending in a third direction from the connecting point. The capacitive coupling elementis disposed with an offset toward the first direction. The strip patternis shorter in length than the strip pattern
