Abstract
A slice flexible antenna comprises two layers of flexible insulation material and a radiated element layer, wherein the radiated element layer comprises separate first conducting structure and second conducting structure. The first conducting structure elicits a feeding terminal and an earth connection terminal, and the second conducting structure elicits an earth connection terminal. The first conducting structure is a fork-shaped structure, and the positions of the two forks that are parallel metal thin bands respectively elicit a splicing ear. The second conducting structure is the foil which keeps the corresponding distance away from the adjacent edge of the first conducting structure, and has the comparative external dimension with the nonadjacent edge of the first conducting structure. The slice flexible antenna can work normally in the applied environment that sticks on the surface of the internally-arranged block battery, the outer shell is closed, and the installation space is a very thin narrow slit.
