Abstract: An antenna module is provided. The antenna module is disposed in an electronic device. The antenna module includes an antenna, a signal processing unit, a first differential mode transformer, a first coaxial cable, and a second coaxial cable. The differential mode transformer is electrically connected between the antenna and the signal processing unit. The first coaxial cable includes first conductive core and first tubular conductor which encompasses the first conductive core. The signals received by the antenna are fed into first end of the first conductive core, and second end of the first conductive core is coupled to the differential mode transformer. The first tubular conductor is grounded. The second coaxial cable includes a second conductive core and a second tubular conductor which encompasses the second conductive core. A second end of the second conductive core is connected to the differential mode transformer. The second tubular conductor is grounded.
