Vertical transition structure from strip line to coaxial line

Abstract

The invention discloses a vertical transition structure from a strip line to a coaxial line. The vertical transition structure comprises a lower dielectric plate, an upper dielectric plate, a bondingpad, a coaxial dielectric outer core, a coaxial probe, a tuning circular seam and a continuous transformation circuit, wherein the continuous transformation circuit is clamped between the upper dielectric plate and the lower dielectric plate; Metallizing via hole are formed in the periphery of the continuous transformation circuit at equal intervals; the coaxial is inserted from the bottom of thelower dielectric plate, and is welded with the bonding pad on the top of the upper dielectric plate after passing through the lower dielectric plate, the continuous transformation circuit and the upper dielectric plate; the coaxial dielectric outer core is used for wrapping the part, which is not inserted into the lower dielectric plate, of the coaxial probe; and the tuning circular seam is positioned on the outer side of the bonding pad. According to the vertical transition structure, the coaxial line and a substrate integrated waveguide are vertically connected by adding the tuning circularseam and the continuous transformation circuit, and electromagnetic waves are transmitted preferably, so that the structural strength and integration level of the transition structure from the substrate integrated waveguide to the coaxial line are improved.

Description

technical field [0001] The invention relates to a transition structure from a strip line to a coaxial line, in particular to a vertical transition structure from a strip line to a coaxial line. Background technique [0002] Stripline is a low-loss, dispersion-free, low-cost form of electromagnetic wave transmission line widely used in modern microwave systems. In order to feed the stripline, it is often necessary to use a transition structure to connect the stripline to the coaxial line. The commonly used transition structure from the stripline to the coaxial line is a horizontal transition structure, that is, the stripline and the coaxial line are on the same horizontal plane. However, the structural strength of this transitional structure is not high, it is easy to be damaged, and the integration degree is not high. Contents of the invention [0003] The purpose of the present invention is to provide a vertical transition structure from a strip line to a coaxial line, ...
