Abstract
An antenna having a plurality of resonant frequencies and including a feed point; a ground point; and an antenna track extending between the feed point and the ground point and including, in series, a first small loop, a large loop and a second small loop. In one embodiment, the extension of the antenna track through the first U-shaped small loop displaces the antenna track in a first direction, then the extension of the antenna track through the large U-shaped loop displaces the antenna track in a second direction opposite to the first direction and the extension of the antenna track through the second U-shaped small loop displaces the antenna track in the first direction. A bridge element may be used.
