HYBRID TYPE DIELECTRIC ANTENNA MULTICOUPLER

摘要

PURPOSE:To cope with mounting with high density and to attain light weight and small size by providing plural dielectric filters having different center frequencies in one and same ceramic substrate. CONSTITUTION:A LPF (low-pass filter) circuit 13 for suppressing a spurious wave and a branching circuit 14 branching plural dielectric filters 15, 15b are formed in the ceramic substrate 10. The dielectric filters 15a, 15b are formed by plural semi-coaxial resonators provide with a frequency adjusting pattern 16 formed to plural pillar center conductors mounted directly on the ceramic substrate 10 and provided to a uniform single substance dielectric.
