  • Patent number: 9093747
    Abstract: The present invention relates to an antenna module for an insert type antenna module for a portable terminal and a method for manufacturing the same. More specifically, the method for manufacturing an insert type antenna module for a portable terminal comprises an antenna radiation part manufacture step wherein an antenna core is manufactured, the antenna core being engaged by an insert so that an antenna radiation part configured in a predetermined shape selected between a plane shape and a curved shape with at least one axis by cutting and bending a conductive metal sheet is exposed toward an outer surface of one side, wherein in the antenna radiation part manufacture step, in the core forming mold is disposed an antenna support protrusion maintaining a gap for the sake of a thickness development of the antenna core.
    Type: Grant

  • Patent number: 8760351
    Abstract: An insert type antenna module for a portable terminal and a method for manufacturing the same are disclosed. The antenna radiation part is formed of a conductive metal sheet having a curve with at least one axis, and the antenna code to which the antenna radiation part is engaged is inject-formed, and a cover is inject-formed at one exposed outer surface of the antenna core in a state that the antenna core is inserted. The present invention is characterized in that in a manufacture of an antenna module for a mobile terminal, a cover is inject-formed at an outer surface of the exposed side of an antenna core in a state that an antenna core to which an antenna radiation part is engaged is inserted.

  • Publication number: 20110254742
    Abstract: An insert type antenna module for a portable terminal and a method for manufacturing the same are disclosed, which make it possible to come up with an easier manufacture of an antenna module and to enhance the durability of an antenna module. The antenna radiation part is formed of a conductive metal sheet having a curve with at least one axis, and the antenna code to which the antenna radiation part is engaged is inject-formed, and a cover is inject-formed at one exposed outer surface of the antenna core in a state that the antenna core is inserted. The present invention is characterized in that in a manufacture of an antenna module for a mobile terminal, a cover is inject-formed at an outer surface of the exposed side of an antenna core in a state that an antenna core to which an antenna radiation part is engaged is inserted, which results in manufacturing a uniform thickness of an antenna module and decreasing a weight, volume and area, thus achieving a lighter and thinner terminal housing.
