A windshield wiper arm is provided with a multi-frequency broadband receiving antenna function so as to reduce the count of antennas to be attached to motor vehicles, aircraft, ship and the like, to thereby reduce the cost related to design and manufacture of antenna and improve operational safety. The combined antenna and windshield wiper arm includes an arm head; a retainer coupled to be rotatable to the arm head and which has a sleeve portion with a closed cross section; an arm piece coupled to an end of the retainer through an electric insulator as a medium; and an elastic member one end of which is coupled to be electrically conductible to the arm piece and the other end of which is coupled to the arm head through an electric insulator as a medium.
