Abstract
This coupler is a coupling line-type coupler having a multilayer configuration in which a plurality of conductor layers are stacked, the coupler comprising first lines and a second line that are formed in the conductor layers different from one another, the first lines being formed in the plurality of conductor layers having interposed therebetween the conductor layer in which the second line is formed, and the first lines and the second line at least partially overlapping one another in the stacking direction of the conductor layers.
Claims9
A coupler being a coupled-line coupler having a multilayer configuration in which a plurality of conductor layers are laminated, the coupler comprising:
- a first line and a second line formed on different ones of the conductor layers,
- wherein the first line is formed on at least two of the conductor layers sandwiching at least one of the conductor layers on which the second line is formed, and
- wherein the first line and the second line at least partially overlap with each other in a lamination direction of the conductor layers.
A Butler matrix circuit comprising:
- a plurality of coupled-line couplers formed on an identical substrate and each having a multilayer configuration in which a plurality of conductor layers are laminated,
- wherein each of the couplers includes a first line and a second line formed on different ones of the conductor layers, the first line being formed on at least two of the conductor layers sandwiching at least one of the conductor layers on which the second line is formed, and the first line and the second line at least partially overlap with each other in a lamination direction of the conductor layers,
- wherein each of the couplers includes an input port, an output port, a coupling port and an isolation port,
- wherein the coupling port of the first coupler is connected to the input port of the third coupler,
- wherein the coupling port of the second coupler is connected to the isolation port of the third coupler,
- wherein the output port of the first coupler is connected to the input port of the fourth coupler, and
- wherein the output port of the second coupler is connected to the isolation port of the fourth coupler.
