This rotary coupler transmits and receives signals (e.g., high-frequency signals) between the fixed portion 10A and the rotating portion 20A using electromagnetic coupling.
- signals e.g., high-frequency signals
- the fixed part 10A and the rotating part 20A are arranged coaxially and are separated from each other with a certain gap in the axial direction.
- the rotating part 20A rotates around the central axis O (see FIG. 2) of the rotary coupler relative to the fixed part 10A.
- the arrow surrounding the central axis O indicates the rotation direction of the rotating part 20A.
- the rotating part 20A can rotate both clockwise and counterclockwise.
- the fixed part 10A has a lossy medium 11, a first waveguide 12a (hereinafter simply referred to as waveguide 12a), a second waveguide 12b (hereinafter simply referred to as waveguide 12b), and a transmission/reception circuit 13.
- the transmission/reception circuit 13 constitutes the fixed side transmission/reception circuit.
- Both the waveguides 12a and 12b are arc-shaped and have the same diameter. Furthermore, the waveguides 12a and 12b are arranged on the same plane and are coaxial with the central axis O. Therefore, the waveguides 12a and 12b are arranged facing each other, and as a whole, they form a substantially circular arc shape.
- One end of the waveguide 12a and one end of the waveguide 12b are connected via a lossy medium 11. Meanwhile, the other end of the waveguide 12a and the other end of the waveguide 12b are each connected to a transmitting/receiving circuit 13.
- the rotating part 20A has a coupling part 21 and a transmitting/receiving circuit 22.
- the transmitting/receiving circuit 22 constitutes the rotating side transmitting/receiving circuit.
- the coupling portion 21 is a transmission line.
- the coupling portion 21 is arc-shaped and has the same diameter as the diameter D of the waveguides 12a and 12b.
- the length of the coupling portion 21 is different from the lengths of the waveguides 12a and 12b. Specifically, the length of the coupling portion 21 is shorter than the lengths of the waveguides 12a and 12b.
- the coupling portion 21 is also arranged coaxially with the central axis O. That is, the waveguides 12a and 12b, and the coupling portion 21 are arranged coaxially. Furthermore, the coupling portion 21 is connected to the transmission/reception circuit 22.
- the coupling portion 21 rotates together with the rotation of the rotating portion 20A around the central axis O. At this time, the coupling portion 21 faces at least one of the waveguides 12a and 12b in the axial direction. Therefore, the coupling portion 21 is electrically coupled to at least one of the waveguides 12a and 12b.

- the signal output from the transmission/reception circuit 13 of the fixed part 10A is in phase with the other end of the waveguide 12a and the other end of the waveguide 12b and is split into two.
- the signal distributed to the other end of the waveguide 12a is transmitted along the length of the waveguide 12a before reaching the coupling section 21.
- the signal distributed to the other end of the waveguide 12b is transmitted along the length of the waveguide 12b before reaching the coupling section 21.
- the signal transmitted from waveguide 12a and the signal transmitted from waveguide 12b are combined in phase because waveguides 12a and 12b are electromagnetically coupled to coupling section 21.
- the combined signal is then transmitted to transmission/reception circuit 22.
- Such a signal that travels from transmission/reception circuit 13, through waveguides 12a and 12b, through coupling section 21, and to transmission/reception circuit 22 is transmitted as a wideband signal without discontinuity in the electromagnetic field distribution.
- the rotary coupler according to embodiment 1 does not cause discontinuity in the electromagnetic field distribution when the coupling unit 21 is placed at a rotational angle position other than directly above the lossy medium 11. Furthermore, when the rotary coupler according to embodiment 1 is placed at a rotational angle position corresponding to directly above the lossy medium 11, the signals from both are combined in phase by electromagnetic coupling between the waveguides 12a, 12b and the coupling unit 21. Therefore, the rotary coupler according to embodiment 1 can transmit and receive signals between the fixed unit 10A and the rotating unit 20A regardless of the rotational angle position of the rotating unit 20A.
- the rotary coupler is a rotary coupler that uses electromagnetic coupling to transmit and receive signals between the fixed part 10A and the rotating part 20A that is rotatably supported by the fixed part 10A.

- the waveguide 12a, the waveguide 12b, and the branch portion 12c are assumed to be microstrip lines, and the lossy medium 11 is assumed to be a terminator. Therefore, the rotary coupler can easily manufacture the waveguide 12a, the waveguide 12b, and the branch portion 12c. Furthermore, by using the lossy medium 11 as a terminator, the rotary coupler can prevent unwanted reflection of signals at the ends of the microstrip lines (the tips of the waveguide 12a and the waveguide 12b).
- the branch portion 12c is formed in a T-shape or a bifurcated shape.
- the base end of the branch portion 12c is connected to the transmission/reception circuit 13.

- the position of the probe is disposed on the rotation radius (diameter dimension D) of the lossy medium 11, the waveguide 12a, the waveguide 12b, and the branch section 12c.
- the rotary coupler is capable of adjusting the position of the probe as appropriate, so long as it is within a range in which the desired amount of electromagnetic coupling can be obtained.
- the transmission line used in the probe may be in a form other than a microstrip line. It is also preferable that the transmission line used in the probe does not resonate at the frequency used. For example, if the transmission line is linear, the length of the transmission line may be set to be equal to ⁇ /2.
- the rotary coupler according to embodiment 2 does not cause discontinuity in the electromagnetic field distribution when the coupling unit 21 is placed at a rotational angle position other than directly above the lossy medium 11.
