Abstract
A one-wavelength loop antenna includes a looped antenna element having a length equivalent to one wavelength related to communication; and a feeding cable for feeding current to a feeding point on the antenna element, wherein an inner conductor is disposed inside an outer conductor in a section between the feeding point and an extraction position of the feeding cable distanced from the feeding point by ⅛ wavelength or more, at least one of the outer and inner conductors functioning as the feeding cable.
