Abstract

PURPOSE:Not only to improve the reproducibility for a certain amount of connection between the resonators but realize a miniaturization of a dielectric filter, by using a dielectric column having a rectangular section. CONSTITUTION:The round internal conductors 51a-1-51a-5 are fixed only on the flat plate 53-1 that forms the bottom surface of a case 53. The rectangular dielectric columns 51-1-51-5 have the insertion holes lengthwise at the center part, and conductors 51a-1-51a-5 are inserted into these holes. Under such conditions, the columns 51-1-51-5 touch the projected electrodes 55a-1-55a-5 plus 55b-1-55b-2 provided on the flat plates 53-3-53-4 of the case 53. These projected electrodes increase the leakage of magnetic field to gaps 52-1-52-4 from resonators since the exposed part 510 of columns 51-1-51-5 is set larger than the masked part 51c. As a result, the amount of connection can be increased between resonators without using any cross structure or comb line connection.
