Abstract

Conventional coaxial wiring devices present a problem in that the management of the manufacturing process therefor is difficult. A coaxial wiring device according to the present invention includes a first member, a second member, and a conductor plate. The first member ( 10 ) and the second member ( 30 ) include, when a line that connects a first port and a second port is denoted by a reference line, a first groove ( 11 ) that has a central point on the reference line and extends in a direction that intersects with the reference line; a second groove ( 12 ) that connects one end (FN 1 ) of the first groove ( 11 ) and the first port; a third groove ( 13 ) that connects the other end (FN 2 ) of the first groove ( 11 ) and the first port and has a shape that is line symmetrical to the second groove ( 12 ) with respect to the reference line; a fourth groove ( 14 ) that connects one end (FN 1 ) of the first groove ( 11 ) and the second port; and a fifth groove ( 15 ) that connects the other end (FN 2 ) of the first groove ( 11 ) and the second port and has a shape that is line symmetrical to the fourth groove ( 14 ) with respect to the reference line.

First claim

The invention claimed is:

1. A coaxial wiring device comprising
a first metallic member,
a second metallic member opposed to the first member,
a conductor plate that is provided to be held between the first metallic member and the second metallic member,
a coaxial wire that is formed in the conductor plate, and
a first port and a second port that are provided on respective ends of the coaxial wire,
wherein:
a high-frequency signal is transmitted between the first port and the second port,
the coaxial wire is formed in a bent shape, and
the coaxial wire is arranged to be centrosymmetric with a point on a line that connects the first port and the second port as a center of symmetry.

2. The coaxial wiring device according to claim 1 , wherein the second port is provided on an antenna that converts a signal input through a waveguide into a signal that propagates on a coaxial.

3. The coaxial wiring device according to claim 1 , wherein the first metallic member and the second metallic member comprise:
a first groove that has a central point on the reference line and extends in a direction that intersects with the reference line;
a second groove that connects one end of the first groove and the first port;
a third groove that connects the other end of the first groove and the first port and has a shape that is line symmetrical to the second groove with respect to the reference line;
a fourth groove that connects the other end of the first groove and the second port; and
a fifth groove that connects one end of the first groove and the second port and has a shape that is line symmetrical to the fourth groove with respect to the reference line.

4. The coaxial wiring device according to claim 3 , wherein a first wire formed in a position corresponding to the first groove, a second wire formed in a position corresponding to the second groove, and a third wire formed in a position corresponding to the fourth groove are formed in the conductor plate.

5. The coaxial wiring device according to claim 4 , wherein a filter is formed in the first wire.

6. A conductor plate being held between a first metallic member and a second metallic member, and the conductor plate comprising:
a coaxial wire that is formed in the conductor plate,
a first port and a second port provided on respective ends of the coaxial wire,
a high-frequency signal is transmitted between the first port and the second port,
the coaxial wire is formed in a bent shape, and
the coaxial wire is arranged to be centrosymmetric with a point on a line that connects the first port and the second port as a center of symmetry.
