Abstract
An electronic device includes an antenna unit having an antenna body having a feed point and a ground point between a first end and a second end. The antenna body has an operating band with a resonance of a first wavelength. An electrical length of the antenna body from the feed point to the ground point is greater than or equal to ¼ and less than ½ of the first wavelength. An electrical length from the first end to the feed point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. An electrical length from the second end to the ground point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. The antenna body is adapted to operate in a slot mode and in a wire mode.
