Claim:
1. An antenna device with continuous bending structure having an extended radiation body at least comprised of a first radiation member, a second radiation member, a third radiation member, a fourth radiation member, and a fifth radiation member; wherein the first radiation member is not connected with the fifth radiation member, but directed toward the fourth radiation member via the bending structure, and every junction region between every two adjacent radiation members forms the bending structure with consistent bending direction, the antenna device comprising: a main region, being a radiation body including at least three L-shaped continuous bending structures covering the first radiation member, the second radiation member, the third radiation member and part of the fourth radiation member; a signal grounding point disposed in the fourth radiation member, and a signal feeding point disposed in the first radiation member; wherein the junction region between the first radiation member and the second radiation member has one L-shaped bending structure, the junction region between the second radiation member and the third radiation member has another one L-shaped bending structure, and the junction region between the third radiation member and the fourth radiation member has one more L-shaped bending structure; and a ground region, being another radiation body having at least one L-shaped bending structure, covering the fifth radiation member and another part of the fourth radiation member; the part of the fourth radiation member within the ground region connected with the part of the fourth radiation member covered by the main region; wherein the junction region between the fourth radiation member and the fifth radiation member has one L-shaped bending structure.
