Abstract
Lines for input/output to be respectively coupled with two resonators formed on a dielectric plate, and a coupling line for polarization to be respectively coupled with two resonators which may be separated from each other by one or more other stages to achieve the jump-coupling between the resonators, are respectively formed on an substrate in order to solve problems including the increase in dead space, the increase in the machining and assembly processes for forming a coupling loop, and the reproductivity of characteristics which are caused by using a cable for jump-coupling in polarizing a dielectric filter of planar circuit type.
