Abstract (en)
[origin: EP0902496A2] The mode filter is used to connect a pair of waveguides of different diameters and consists of a tapered tube (4) with openings at each end that have flanged inserts (5,6) to suit the waveguides. Flat blade elements (14,15) are located in slots on opposite sides and minimize unwanted electromagnetic wave effects. These are spaced a specific distance and are produced of an electrically conducting metal.
