Builtin antenna assembly of wireless communication terminals

A built-in antenna assembly of a wireless communication terminal is provided to secure the credibility of contact of a terminal by simplifying a design for the terminal part to be electrically contacted to a substrate when the substrate of a built-in antenna is mounted. In a built-in antenna assembly of a wireless communication terminal, a base(110) is mounted on a substrate(P). A radiator(120) is fixed on an upper surface of the base(110) to transmit and receive a signal. A terminal part(130) earths and supplies power to the radiator(120), when the terminal part(130) is contacted to a contacting pad part, by being elongated along an outer surface of the base(110). A terminal suspending part fixes a free end of the terminal part(130) to the base(110).
