MICROWAVE CIRCUIT

Document Type and Number:

WIPO Patent Application WO/1992/004744

Kind Code:

A1

Abstract:

A conductive strip (1) of an MSL is connected with the internal conductor of a coaxial line provided with a metallic case (3) as its external conductor, via a through hole (9) bored in a dielectric substrate (2) from an MSL grounding surface (11) which is provided on the dielectric substate (2). A ring-like protruding part (7) is formed on the metallic case and is in contact with the grounding surface (11). Thereby, the external conductor of the coaxial line is reliably in contact with the MSL grounding surface (11). Since there is no mismatching part, the loss and the deterioration of VSWR in the MSL converting part and the coaxial line can be prevented, and desirable characteristics are obtained.
