Electronic device and antenna module thereof

An antenna module is provided. The antenna module includes a first ground element, a body, a radiator and a bending parasitic element. The body is electrically connected to the first ground element. The radiator is connected to the body, wherein the radiator includes an extending portion, a bending portion and a terminal extending portion, and the bending portion is connected to the extending portion, and the terminal extending portion is connected to the bending portion. The bending parasitic element includes a parasitic extending portion and a parasitic conductive portion, wherein the parasitic extending portion is connected to the parasitic conductive portion, and the terminal extending portion and the parasitic extending portion are located on a same straight line, and the terminal extending portion is separated from the parasitic extending portion. By applying the antenna module of the embodiment of the present invention, the two communication specifications of LTE and Penta band can be satisfied in a sw
