ABSTRACT:
Provided is a signal transmission line for a millimeter-wave band. The signal transmission line includes: a dielectric substrate; an input line formed on the dielectric substrate; a pair of serial transmission lines formed on the dielectric substrate, the serial transmission lines being branched at, separated from, and electromagnetically connected in series with one end of the input line; a pair of parallel transmission lines respectively formed on the dielectric substrate at both sides of the input line and the serial transmission lines, and having both ends separated from and electromagnetically connected in parallel with one end of each of the input line and the serial transmission lines; and a pair of wires electrically connected between the other ends of the parallel transmission lines and a connection pad of a monolithic microwave integrated circuit (MMIC). An electrical signal of about 57 to 63 GHz generated from a monolithic microwave integrated circuit (MMIC) can be efficiently transferred.
