Abstract

The invention discloses a method for realizing conversion between metal rectangular waveguides and microstrip lines. The device comprises a waveguide converter and a microstrip line converter connected with the waveguide converter. The waveguide converter comprises a waveguide section and a waveguide transition section, wherein the waveguide section comprises a wide edge and a narrow edge; the waveguide transition section is formed by retracting the narrow edge of the waveguide section to a connecting surface between the waveguide converter and the microstrip line converter in a linear lowering way; and a dielectric body is uniformly filled into the wide edge of the waveguide section. The microstrip converter comprises a baseband board and the microstrip lines, wherein the width of the baseband board is the same as that of the metal rectangular waveguide; and the microstrip lines are arranged on the baseband board. Electromagnetic waves are transmitted from the waveguide converter to the microstrip line converter to realize effective conversion between waveguide propagation and microstrip line propagation. The device only relates to a linear planar structure, is simply structure and simple and convenient to manufacture; moreover, a frequency-sensitive geometrical structure is unrelated, and the working frequency range of the device is only limited by own working frequency range of the waveguide, so the device has the characteristic of wideband.

Description

technical field [0001] The invention relates to the technical field of electromagnetic wave transmission, in particular to a conversion device and a conversion method between a metal rectangular waveguide and a microstrip line. Background technique [0002] In the field of electromagnetic wave transmission, especially in the process of microwave or millimeter wave transmission, it is usually necessary to transmit microwave signals between waveguides and microstrip lines. Between the energy conversion device. [0003] In the prior art, a converter between a microstrip line and a metal rectangular waveguide adopts a flat plate structure. A through hole is provided at the intersection of the plate and the metal rectangular waveguide. The independent piece includes a microstrip line terminal and can be placed on the through hole. An adjustment is made so that the end of the microstrip line coincides with the end of a microstrip line on the plate. The conversion device has a co...
