Abstract

PURPOSE:To attain small size and light weight by forming the inner and outer conductors by a conductor film in close contact with a dielectric block and using an inner conductor coupling means so as to couple the inner conductors. CONSTITUTION:The inner conductor 16 of nearly 1/2 wavelength is formed by a conductor film in close contact with the inner circumferential face of plural throughholes 14 made to the dielectric block 13 and the outer conductor 15 is made by a conductor film in tightly contact onto the outer peripheral face other than the aperture of the throughholes 14 and slots 17, 18 acting like the inner conductor coupling means are provided at least on one of flat and bottom faces of the dielectric block 13 are provided. Moreover, an input/ output coupling means 7 is coupled with the prescribed inner conductor and an electrostatic coupling means 8 coupled electrostatically with each of the innerconductors is provided to a position apart from the input/output coupling means 7 and connected by a connection line 9. Thus, the inner conductor 16, the outer conductor 15 and the dielectric block 13 are incorporated to save number of components and facilitate the manufacture and assembling, the necessity of the function of the case to the outer conductor is eliminated to attain small size and light weight.
