。Problems to be Solved by the Invention However, in the case shown in Fig. 4, the dielectric coaxial resonator 9.10
Coupling between them is performed by a capacitor 13Vc outside the dielectric coaxial resonators 9.10, and the fact that the capacitor 13 is external in this way and that the cylindrical dielectric coaxial resonators 9.10 are arranged side by side. Otherwise, unnecessary space will be created between them.
Therefore, there was a problem in that it was difficult to make it into a car shape.
本発明はかかる点に鑑みてなされたもので、小形のフィ
