Abstract
The disclosure is related to a printed coupled-fed multi-band antenna, and a related electronic system. The antenna includes a first antenna member structurally with a mushroom-shaped radiation portion and an antenna connection portion being electrically connected with a ground plane. The mushroom-shaped radiation portion is employed to activate first band electromagnetic wave. The antenna includes a second antenna member, which may be shaped as a U-shaped radiation portion. The second antenna member is floating within a region surrounded by the mushroom-shaped radiation portion, the antenna connection portion and the ground plane. The U-shaped radiation portion is coupled with both the ground plane and the mushroom-shaped radiation portion. The coupling effect allows the second antenna member to activate a second band electromagnetic wave. The multiple band signaling paths are formed over the printed antenna for application of a multi-band antenna.
