US 10,476,120 B2 · Multi-port phase shifter with multiple lines formed on opposite surfaces of a ground

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.

Dependent claims

A multi-port phase shifter comprising:

a ground;
a first line formed at a first surface of the ground;
a second line formed at a second surface of the ground, the second surface of the ground being a back side surface opposite to the first surface of the ground;
a third line spaced apart from an upper surface of the first line by a predetermined distance and a portion of the third line being arranged to face the upper surface;
a fourth line spaced apart from a lower surface of the second line by a predetermined distance and a portion of the fourth line being arranged to face the lower surface;
a via hole formed through the ground;
and
a feed line formed on the first surface of the ground so as to include an area where the via hole is formed,
wherein the second line receives an input signal through a coupling effect with the via hole included in the feed line.
