  • Patent number: 10476120
    Abstract: A multi-port phase shifter includes a ground, a first line on one surface of the ground, a second line on the other surface of the ground, a third line spaced at a predetermined distance from the upper surface of the first line and facing a part of the first line, and a fourth line spaced at a predetermined distance from the upper surface of the second line and facing a part of the second line. A via hole penetrates the ground. A power supply line on the one surface of the ground includes a region having the via hole. Multiple ports make the phase shifter applicable to a sector antenna for obtaining a high gain. Phase shifter volume can be reduced by implementing multiple ports in one phase shifter without coupling two or more phase shifters, thereby eliminating an additional component such as a fixing pole or a connecting pole.
