Abstract
An antenna body part for use in an antenna device using a separate metal shield as ground plane is manufactured by forming a first part of the dielectric body by injection molding where a first resin is injected into a first cavity in the injection molding tool; forming a composite dielectric body by injection molding where a second resin injected into a second cavity in the injection molding tool, said first part of the dielectric body is placed in the second cavity as a core for becoming an integrated part of the composite body; and coating a metallic layer onto the surface of the composite dielectric body where said first and second resins are selected to have different adhesive properties for the metal coating so one of the resins repels the metallic layer while the other allows the metallic layer to adhere.
