A bendable antenna is provided. The bendable antenna is adapted to connect a cable. The bendable antenna includes an antenna body, a connection base, a first pivot base, a second pivot base, a first elastic element and a first restriction structure. The connection base is connected to the antenna body. The first pivot base is connected to the connection base, wherein the first pivot base includes a first recess. The second pivot base pivots on the first pivot base. The first elastic element is disposed in the first recess of the first pivot base, wherein the first elastic element is telescoped on the cable. The first restriction structure is connected to the connection base, wherein the first restriction structure pushes the first elastic element to restrict the first elastic element in the first recess.
