Claims

[Scope of utility model registration request]

A rectangular waveguide whose opening at one end is connected to an external transmission path and whose other end is electrically short-circuited by a movable shorting plate, and a pair of holes provided in the center of the wide faces of the rectangular waveguide facing each other. a first external conductor cylinder and a second external conductor cylinder connected to each other so as to protrude outward in a right angle direction; a shorting plate that airtightly closes an end of the second external conductor cylinder; and an inner side of the surface external conductor cylinder. an inner conductor that is inserted into the second outer conductor cylinder and is electrically and mechanically coupled and held to the shorting plate at the outer short end of the second outer conductor cylinder to constitute a coaxial line; and an inner conductor that is located inside the rectangular waveguide. the movable short-circuit plate and the rectangular waveguide behind it; A space for storing cooling air is formed between the tube end and the plate, and a hole for introducing the cooling air is provided in a part of the end plate, and a ventilation hole formed in the movable short circuit plate or A high frequency coupler characterized in that the high frequency coupler is configured such that cooling air is applied to the outer peripheral surface of the dielectric cylinder from a gap between an electrical contact piece attached between the inner wall of the rectangular waveguide and the inner wall of the rectangular waveguide.
