PURPOSE: An antenna coupler of a wireless mobile communication terminal test device is provided to have a coupling tube for coupling wireless signals outputted from an antenna, and to have an electronic shielding unit for shielding electromagnetic waves by covering the coupling tube, thereby reducing coupling loss and leaking electromagnetic waves. CONSTITUTION: A coupler(200) comprises as follows. A coupling tube(240) receives wireless signals outputted from a terminal antenna. An electronic shielding unit is insulated with the coupling tube(240), and covers the coupling tube(240), to prevent electromagnetic waves from being outputted. The electronic shielding unit comprises as follows. An electronic shielding tube(210) locates the coupling tube(240) in an empty part. A cover plate(230) is coupled with one end of the coupling tube(240), and is coupled by using an upper surface of the electronic shielding tube(210). A cover ring(220) is formed on the other end of the electronic shielding tube(210).
