PROBLEM TO BE SOLVED: To provide a thin type rotary joint having broadband characteristics, low losses, and high power resistances. SOLUTION: The rotary joint comprises a first and second polarized wave separators and a circular or square waveguide having a rotatable connection part. Each wave separator has a common terminal having a circular or square waveguide sectional shape and two branch terminals for separating and taking two mutually orthogonal polarized waves inputted to the common terminal. The waveguide is connected at one end to the common terminal of the first wave separator and at the other end to the second wave separator. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To create a rotatable connector of an arbitrary length without at least considerable development. SOLUTION: In the high frequency rotatabe connector with a stator 1, the stator is coupled with at least one rotor 2 in high frequency manner via one λ/4 conducting wire and at least partially surrounds the rotor, and the rotor 2 is supported within the stator 1 without contact by at least one radial air bearing and at least one axial air bearing.

PROBLEM TO BE SOLVED: To reduce a mechanical load and further reduce a manufacturing cost, by simplifying the structure. SOLUTION: Two circular waveguides 1, 3 having TM01 propagation modes are disposed on the same axis, and a waveguide side chalk 4 is provided therebetween. Further, a rectangular waveguide 2 is connected to the fixed side circular waveguide 1 while a primary radiator 5 is connected to the rotating side circular waveguide 3. Hereby, a high-frequency signal supplied from the rectangular waveguide 2 to the fixed side circular waveguide 1 can be radiated from the primary radiator 5. Furthermore, a rotary joint can be constituted of the circular waveguides 1, 3 and the waveguide side chalk 4, and the high-frequency signal radiated from the primary radiator 5 can be scanned by rotating the primary radiator 5 together with the rotating side circular waveguide 3.
