Abstract: A method for controlling dielectric constant of a composite material through micro pattern printing includes setting a dielectric constant value needed in the composite material, preparing a paste having an electromagnetic loss material, fabricating a composite material sheet by forming the paste on one surface of a base member in a predetermined pattern, and fabricating the composite material sheet with the micro patterns including the electromagnetic loss material on the base member by drying the composite material sheet, wherein the base member is formed of a sheet and includes fibers.
