  • Publication number: 20150048994
    Abstract: An antenna module includes: a first injection-molded part which is formed to have a base portion and a protrusion portion to be protruded from the base portion by an injection molding; an antenna pattern which is positioned on the protrusion portion; and a second injection-molded part which is formed to cover the antenna pattern by an injection molding. Since the antenna pattern is formed on the protrusion portion of the first injection-molded part, the thickness of a portion of the second injection-molded part on the antenna pattern can be minimized, and accordingly the antenna module and the mobile terminal case can be formed to be thin, light-weight and slim while the transmitting/receiving efficiency of the antenna can be maximized.
