Abstract:
1. An antenna having a conducting wire part comprising: a first part extending in a first direction; a second part extending from an end of the first part in a second direction perpendicular to the first direction; and a third part extending from an end of the second part in the first direction to face the first part and being parallel to the first part, and the first part and the third part being separated by a length of the second part, wherein lengths of the first and third parts are different from each other, the first and third parts are formed in meander lines, the meander line of the first part having the same shape, pitch, and meander width as the third part, the meander line of the first part are offset in the first direction from the meander line of the third part, wherein the meander line of the first part is shifted from the meander line of the third part along the first direction to control a capacitance between the first part and the third part, by a shift width, which is a distance between sections of the meander line of the first and third parts in the first direction, and wherein the antenna attaches electrically to a device at an end of the first part opposite to the end of the first part where the second part is attached.
