Embodiment Construction

[0023] Conversion structure between rectangular coaxial line and microstrip line, such as figure 1 , figure 2 and image 3 shown.

[0024] Such as figure 1 As shown, the microstrip line is placed above the rectangular coaxial line, and the ground metal plate of the microstrip line is reliably electrically connected to the outer conductor of the rectangular coaxial line.

[0025] Such as figure 2 As shown in the figure, a metal wall is added to one end of the rectangular coaxial line to form a closed structure at the end of the rectangular coaxial line, and a square hole is opened above the coaxial line at the connection with the microstrip line.

[0026] Several larger metal columns are used to connect with the microstrip line grounding metal plate, and the height of the metal columns is equal to the height of the rectangular coaxial line, so as to realize the mechanical support for the microstrip line.

[0027] Such as image 3 As shown, a slot is made on the ground m...

Abstract

The invention discloses a transition circuit for a rectangular coaxial line and a micro-strip, and belongs to transition technologies for microwave and millimeter waves between rectangular coaxial lines and micro-strips. The transition circuit comprises a metal carrier, a micro-strip line, a micro-strip line support metal column, the rectangular coaxial line, a connecting metal column, a micro-strip line dielectric through hole and a compensation metal strip. The transition circuit has the advantages that electromagnetic signals can be transmitted between the rectangular coaxial line and the micro-strip line on the basis of micro-strip compensation structures and LC filter principles, and the transition circuit is smart in design, simple in structure, convenient to debug, low in insertion loss and good in stationary wave characteristic.

Description

technical field [0001] The present invention designs a transition conversion circuit suitable for rectangular coaxial lines and microstrip lines in the millimeter wave frequency range, specifically, it designs a transition between rectangular coaxial lines and microstrip lines with vertical conversion and corresponding compensation structures conversion circuit. Background technique [0002] In recent years, the development of microwave integrated circuits and microwave microsystems has been very rapid, which has greatly promoted the multi-function and miniaturization of microwave devices, and at the same time put forward higher requirements for microwave transmission lines: higher application frequency, smaller transmission loss, The size is more compact. The transmission lines such as microstrip lines, coplanar waveguides, and grounded coplanar waveguides commonly used in existing microwave integrated circuits have relatively large electromagnetic coupling and radiation l...
