PURPOSE:To obtain a filter featuring a high measurement accuracy in an easy way by attaching the conductor films of a fixed form to the dielectrics and the then arraying the dielectrics into the waveguide. CONSTITUTION:Dielectric plate 3 and 3' are located vertically to the tube axis of waveguide 1' and conductor film 4 and 4' are coated through evaporation onto the surface which is orthogonal to the tube axis of plate 3 and 3'. Furthermore, dielectric 5 is installed. The space between film 4 and 4' is determined by the thickness of plate 3 and 3' plus 5. Plate 3 and 3' plus 5, are polished accurately right before they are put into waveguide 1' and thus their thickness can be kept accurate. Thus, a filter of a high measurement accuracy can be obtained in an easy way. |
