摘要： PROBLEM TO BE SOLVED: To obtain a filter which has sufficient filter characteristics in a high frequency band by providing an island-shaped conductor film on the surface of a dielectric block with an interval in a longitudinal direction, providing conductor films over almost the entire residual part of the surface and the other surfaces separating and insulating from the conductor film and extending a through hole on a surface which faces a surface on which input-output electrodes are formed. SOLUTION: Input-output electrodes 11 and 12 which are constituted of an island- shaped conductor film are formed on a surface that is the widest area of a dielectric block 10 of a rectangular parallelepiped with an interval placed and they are input- output electrodes. A conductor film 13 which surrounds the electrodes 11 and 12 around the electrodes 11 and 12 with 0.5 mm interval placed is formed over almost the entire surface except of the residual surface. Also, a conductor film is formed on all of the other surfaces except the surface on which the electrodes 11 and 12 are formed and is made conductive with the electrodes 11 and 12 that surround the film 13 and the whole is made a ground electrode. The electrodes 11 and 12 are connected to an input-output signal line. A through hole which extends to an opposite surface from the surface is formed between the electrodes 11 and 12.

摘要： PURPOSE:To realize a small sized resonator and filter requiring no adjustment, which is used for a high frequency band over 100MHz. CONSTITUTION:Conductor strip lines 11-14 each having one turn or over are formed to one side or both sides of a dielectric board 10 whose dielectric constant is comparatively high and a line capacitor is formed by making the conductor strip lines 11-14 close to each other or opposite to each other on the front side and the rear side so as to generate line capacity. One terminal is connected to an input/output terminal and the other end is opened. An LC parallel resonance circuit is formed by an inductance component of the conductor strip lines 11-14 and the line capacitor of the conductor strip lines 11-14 and the filter is obtained by forming the circuits in multi-stage. The input/output coupling capacitor is obtained by using the ends of the conductor strip lines 11, 13 and the conductor patterns 15, 16 on the rear side. Thus, the filter is obtained, which has an attenuation pole by one open end.
