HIGH-FREQUENCY TRANSMISSION LINE, DIELECTRIC RESONATOR, FILTER, DUPLEXER, AND COMMUNICATION DEVICE

摘要

The invention provides a high-frequency transmission line and a dielectric resonator having a small size and having an effectively reduced loss. When a transmission line is produced, an electrode is formed on a dielectric plate in such a manner that one or more gaps are formed in an edge portion of the electrode along an edge of the electrode thereby forming thin line-shaped electrodes whereby a current which would otherwise be concentrated to a great extent in the edge portion of the electrode is divided into a plurality of portions.
