Claims

[Claims for Utility Model Registration] (1) In order to be sandwiched between two waveguide flanges each having a waveguide opening of the same shape, a window having the same shape as the waveguide opening is provided, and the waveguide A spacer for preventing radio wave leakage, characterized in that it is made of a metal plate having a metal thin film attached to both sides, which is softer than a flange and surrounds the entire circumference of the window in a band shape. (2) A utility model registration request in which the metal plate is softer than the waveguide flange and has a strip-shaped thin metal film attached to both sides of the outer periphery of the overlapped portion of the two waveguide flanges. Range of the radio wave leakage prevention spacer described in item 1.
