Abstract
This invention provides novel combline resonators with multiple conductors and multiple dielectrics for compact filters and multiplexers with improved electric response. The novel combline resonator consists of multi-conductors being made up for the simplest case of an inner metallic post, an intermediate conductor, and an enclosure. This structure provides two resonant modes that can be used for realizing compact microwave filters and multiplexers. Such filters offer the low cost, compact size and ease of manufacturing features of traditional combline resonator filters, with additional size reduction due to the fact that a single physical cavity provides two electrical resonators. In addition, the new cavity inherently introduces a transmission zero in the guard-bands enhancing the filter selectivity.
