Abstract: A power divider includes a substrate. The substrate includes an input terminal, a microstrip, a short-circuit stud, an open-circuit stud, a first output terminal and a second output terminal. One end of the microstrip is electrically connected to the input terminal. One end of the short-circuit stud is electrically connected to the microstrip. The first output terminal is electrically connected to the other end of the microstrip and the open-circuit stud. The second output terminal is electrically connected to the other end of the microstrip. Through impedance matching of the open-circuit stud at the first output terminal, the range of the radiated electric field at the second output terminal is reduced, and the bend slope attenuation may be carried out under the wide frequency band of 700 MHz. Therefore, the radiated electric field of the antenna can still be reduced without adjusting the antenna gain in a wide frequency band.
