IPC: H01P1/205
Filed: 1984-07-18
Abstract: PURPOSE:To realize small size and narrow band by inserting a conductor film formed incorporatedly with a dielectric substrate between strip conductors so as to decrease the coupling degree between the strip conductors. CONSTITUTION:One end of plural strip conductors (conductor layers) 11-14 in parallel with the surface 10A of a square dielectric substrate 10 is made coincident with a long ridge 10a of the surface 10A and the lengthwise direction is made in parallel with a short ridge 10b by coating. Cut slots 21-23 are cut in parallel with the strip conductors 11-14 at nearly middle position of the strip conductors 11-14 and the length is made nearly equal to the length of the, e.g., strip conductors. After baking of the substrate 10, through-hole plating is applied to side walls 21a-23a of the cut slots 21-23 and end faces 10C-10F of the substrate 10 and the conductors (conductive layers) are coated incorporatedly. The degree of coupling among the strip conductors 11-14 is decreased by the shield effect of the conductor coating film of side walls 21a-23a of the cut slots 21- 23 inserted among the strip conductors 11-14.
