Claims

[Scope of utility model registration request]

(1) In a waveguide device in which a high frequency filter is interposed between the connecting flanges of the first and second waveguides, the high frequency filter is arranged on one surface of a thin plate made of a dielectric material in order to pass only a desired frequency component. A metal film is formed leaving a passing portion with set dimensions, and a metal film is formed on the other side only in the portion that contacts the waveguide flange, and is electrically conductive with the metal film. and a second waveguide, the waveguide device being airtightly interposed between the connection flanges of the second waveguide.

(2) The waveguide device according to claim (1), wherein at least one of the first and second waveguides is configured in an airtight state.

(3) A claim for utility model registration characterized in that the waveguide configured in an airtight state has a recess formed on the connecting flange surface, and a high frequency filter is fitted into this recess and fixed airtightly. The waveguide device according to scope (2).
