Abstract

The invention discloses a manufacturing method of a 2*2 single-side double-fin linear array based on square wave guide, comprising the following steps of establishing a simulation model of the 2*2 single-side double-fin linear array and carrying out simulation to the simulation model to obtain the scattering property of the 2*2 single-side double-fin linear array; applying the Klopfenstein theory in a fin line structure, and obtaining a fin line structure with the fixed length and minimum reflection coefficient according to a numeric iteration method and obtaining effective dielectric constants corresponding to transverse nodes of the double fin lines by commercial calculation software; combining the effective dielectric constants with the scattering property, obtaining the width of fin slot corresponding to different nodes of the fin line, further obtaining a conversion curve of the fin slot of the fin line with the transverse nodes, drawing the curve by commercial drawing software and obtaining an optimized 2*2 single-side double-fin linear array based on the square wave guide. The manufacturing method effectively avoids complicate numerical calculation, adopts mature electromagnetic field simulation software and shortens design period.

Description

technical field [0001] The invention relates to the technical field of design of microwave and millimeter wave band planar transmission lines, in particular to a method for manufacturing a 2×2 single-sided double-fin line array based on a square waveguide. Background technique [0002] In various application systems of microwave and millimeter wave, such as: radar, guidance, remote sensing and communication systems, as its main component, millimeter wave solid-state power amplifier is like the "heart" of these devices, and has become the most important field of millimeter wave research research direction. [0003] Traveling wave tube amplifier (TWTA) is currently the most widely used millimeter wave power source due to its advantages of high power, broadband and high efficiency. However, TWTA itself has inherent disadvantages such as large volume, heavy weight and high cost. With the development of MMIC technology, solid-state microwave and millimeter-wave amplifiers show ...
