Abstract

PURPOSE:To obtain a filter reducing loss and having a wide passing band or stopping band by using suspended lines and a dielectric rod to be penetrated into a hole formed on a dielectric substrate and holes of dielectric resonators. CONSTITUTION:The suspended strip lines 6a, 6b and 6c, 6d are symmetrically arranged on both the faces of the dielectric substrate 18. The dielectric resonators 7a, 7b and 7c, 7d are also symmetrically arranged on both the faces of the substrate 1 and the dielectric rod 8 is penetrated into the holes of the resonators 7a-7d and the hole formed on the substrate 1. Thereby, an electromagnetic field is concentrated into a space formed between the lines 6a-6d and a case to be a ground conductor and is not influenced by the substrate 1, so that the loss can be extremely reduced. In addition, conductive loss can be reduced and a large non-load Q can be obtained.
