摘要： The present invention provides a small dielectric filter suitable for use in a high frequency band equal to or higher than 3 GHz. an input/output electrode made up of island type of conductive film is formed on one surface of said dielectric located on each end portion; in each of said dielectrics located on each end respectively, an earth electrode is formed on almost of all remaining area of said surface so as to be isolated from said input/output electrode and is also formed on all of the other surfaces with an exception of connecting surfaces; in an intermediate dielectric, an earth electrode is formed on all surfaces other than the connecting surface; and a conductive film connected to the earth electrode is formed on a part of at least one of the connecting surfaces of the dielectrics to be connected. Three or more elements of resonators may be integrally formed on a dielectric block, and, in that case, a through-hole is formed between the resonators.

摘要： The present invention provides a dielectric waveguide filter comprising a plurality of dielectric waveguide resonators in the form of rectangular parallelepiped-shaped blocks aligned as a single main body having opposite ends defined by respective the end blocks located thereat, and a pair of input and output electrodes provided in the end blocks, respectively. Each of the end blocks is formed with a protruding portion including a dielectric substance extended from that therein. A conductive strip line extending from the bottom surface of corresponding one of the end blocks to the edge region of the bottom surface of corresponding one of the protruding portions. The bottom surfaces have a region where the dielectric substance in contact with the both sides of the conductive strip line is exposed to outside. The conductive strip lines are coupled with micro-strip lines or co-planer lines on a printed circuit board having a given length to obtain an adequate matching between input and output signals.
