Abstract

PURPOSE:To obtain a filter which is lightweight and easy to manufacture by forming a plate conductor made of a thin copper into a case where a one face among six faces is opened and providing an induction window to a face opposed to the open face of the case so as to form a unit waveguide. CONSTITUTION:Conductor plates 1-6 are cut off from a thin plate conductor made of copper (0.2-0.3mm thick), the induction window 7 is provided and slots 8-11 are applied. Then the plate is folded in a direction opposite to the slots along the slots 8, 9, 10 and 11 and the conductor plates are connected electrically and mechanically by a method such as soldering to constitute a box-shaped unit conductor whose one face is opened. The size of the entire face including the conductor plates 5, 6 and the induction window 7 is decreased more then the size of the opened face, the face including the induction window of the unit waveguide 13 is fitted to the open face of the unit waveguide 12 and the other unit waveguides are fitted together, resulting in combining the six unit waveguides with each other.

According to the present invention, since the unit waveguides constituting the waveguide filter are made of thin plate-shaped conductors, the wall thickness of the waveguide filter can be made thin, and the weight of the entire filter can be reduced. Additionally, since the wall thickness of the surface with the guide window, which is comparable to a conventional partition plate, can be made thinner, it is possible to bring the filter characteristics closer to the theoretical value. In addition, since the waveguide filter is constructed by combining a plurality of unit waveguides having a simple structure, it can be easily manufactured, and is therefore effective in reducing costs.

This will lead to an improvement in the processing density.
