Abstract

An electronic circuit includes at least two first conductors having line shapes which are arranged on a first plane of a substrate, a second conductor arranged on a second plane of the substrate, and a third conductor having a line shape, with at least part thereof being arranged on a third plane between the first plane and the second plane of the substrate. The open end of the third conductor is included in part of the third conductor which is arranged on the third plane, and the part is arranged to at least partly overlap one of at least the two first conductors and not to overlap the other first conductor when viewed from a direction perpendicular to the substrate.

First claim

What is claimed is:

1. An electronic circuit comprising:
at least two first conductors having line shapes which are arranged on a first plane of a substrate;
a second conductor arranged on a second plane of the substrate; and
a third conductor having a line shape, with at least a part thereof being arranged on a third plane between the first plane and the second plane of the substrate,
wherein the third conductor is arranged such that the part, in the third plane, at least partly overlaps one of the at least two first conductors and does not overlap another one of the at least two first conductors when viewed from a direction perpendicular to the substrate, while the part includes an open end of the third conductor, and wherein each of the at least two first conductors is a signal line and the second conductor is a ground conductor, and
wherein the third conductor includes a portion different from the part which is arranged on a fourth plane between the third plane and the second plane.

2. The circuit according to claim 1 , wherein the part of the third conductor arranged on the third plane at least partly has one of a meander shape and a spiral shape.

3. The circuit according to claim 1 , wherein two or more of the third conductors respectively corresponding to the at least two first conductors are comprised in the circuit.

4. The circuit according to claim 1 , wherein the portion is connected to the second conductor.

5. The circuit according to claim 1 , wherein the portion includes a second open end different from the open end of the third conductor.

6. The circuit according to claim 1 , wherein the portion is arranged to overlap the one of the at least two first conductors and not to overlap the another one of the at least two first conductors when viewed from the direction perpendicular to the substrate.

7. The circuit according to claim 1 , wherein the portion includes a portion which overlaps each of the at least two first conductors when viewed from the direction perpendicular to the substrate.

8. The circuit according to claim 1 , wherein the portion at least partly has one of a meander shape and a spiral shape.

9. An electronic circuit comprising:
at least two first conductors having line shapes which are arranged on a first plane of a substrate;
a second conductor arranged on a second plane of the substrate; and
a third conductor having a line shape arranged between the first plane and the second plane of the substrate,
wherein one of end portions of the third conductor is connected to one of the at least two first conductors and the other of the end portions is an open end which is arranged nearer to the second plane than the first plane, and wherein each of the at least two first conductors is a signal line and the second conductor is a ground conductor, and
wherein the third conductor at least partly has one of a meander shape and a spiral shape.

10. An electronic circuit comprising:
at least two first conductors having line shapes which are arranged on a first plane of a substrate;
a second conductor arranged on a second plane of the substrate; and
a third conductor having a line shape, with at least a part thereof being arranged on a third plane between the first plane and the second plane of the substrate,
wherein two end portions of the third conductor are connected to the second conductor, and the part is arranged on the third plane to at least partly overlap one of the at least two first conductors and not to overlap another one of the at least two first conductors when viewed from a direction perpendicular to the substrate, and wherein each of the at least two first conductors is a signal line, the second conductor is a ground conductor, and the third conductor does not connect to any one of the at least two first conductors, and
wherein the third conductor at least partly has one of a meander shape and a spiral shape.

11. The circuit according to claim 10 , wherein the third conductor includes a portion different from the part, which is arranged on a fourth plane between the third plane and the second plane.

12. The circuit according to claim 10 , wherein the third conductor includes a portion different from the part, which is arranged on the second plane.

13. An electronic circuit comprising:
at least two first conductors having line shapes which are arranged on a first plane of a substrate;
a second conductor arranged on a second plane of the substrate; and
a third conductor having a line shape, with at least a part thereof being arranged on a third plane between the first plane and the second plane of the substrate,
wherein the third conductor is arranged such that the part, in the third plane, at least partly overlaps one of the at least two first conductors and does not overlap another one of the at least two first conductors when viewed from a direction perpendicular to the substrate, while the part includes an open end of the third conductor, and wherein each of the at least two first conductors is a signal line and the second conductor is a ground conductor, and
wherein the third conductor includes a portion different from the part which is arranged on the second plane.

14. The circuit according to claim 13 , wherein two or more of the third conductors respectively corresponding to the at least two first conductors are comprised in the circuit.

15. The circuit according to claim 13 , wherein the part of the third conductor arranged on the third plane at least partly has one of a meander shape and a spiral shape.

16. The circuit according to claim 13 , wherein the portion at least partly has one of a meander shape and a spiral shape.

17. The circuit according to claim 13 , wherein the portion includes a portion which overlaps each of the at least two first conductors when viewed from the direction perpendicular to the substrate.

18. The circuit according to claim 13 , wherein the portion is connected to the second conductor.

19. The circuit according to claim 13 , wherein the portion includes a second open end different from the open end of the third conductor.

20. The circuit according to claim 13 , wherein the portion is arranged to overlap the one of the at least two first conductors and not to overlap the another one of the at least two first conductors when viewed from the direction perpendicular to the substrate.
