摘要： A printed circuit board and a method of manufacturing the printed circuit board are disclosed. The printed circuit board can include: an optical waveguide, in one side of which a circuit pattern and a pad are buried; an insulation layer stacked over one side of the optical waveguide; a first insulating material stacked over the insulation layer; a first electrical wiring layer stacked over the first insulating material; a second insulating material stacked over the other side of the optical waveguide; a second electrical wiring layer stacked over the second insulating material; and a via penetrating the optical waveguide. Certain embodiments of the invention enable the efficient transmission of optical and electrical signals, reduce loss in the optical signals transferred to the photoelectric converters, and allow more efficient designs for the wiring in the board.

摘要： Disclosed is an internal antenna that provides impedance matching for multiple bands. The antenna includes an impedance matching part, which in turn includes a first conductive element electrically coupled to a feeding point and a second conductive element electrically coupled to a ground, and at least one radiator electrically coupled to the first conductive element, where the first conductive element and the second conductive element of the impedance matching part are separated by a particular distance to perform coupling matching and are electrically coupled at a pre-designated position. Certain aspects of the present invention can be utilized to provide wide band characteristics in designing for multi-band applications, even for high-frequency bands.
