Embodiment Construction

[0024] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] figure 1 A schematic diagram showing the load structure of the inclined plane absorbing array of this embodiment, its top view is as follows figure 2 Shown: Includes SIW lossy transmission line and sloped absorbing array.

[0026] On the traditional SIW transmission line, 22 rows of metallized holes are set, and the 22nd row of metallized holes is a through hole, and each row of metallized holes corresponds to the two rows of metallized through holes of the SIW transmission line on the same straight line.

[0027] The metallized holes and metallized through-holes in the inclined-plane absorbing array take their axis as the physical center, and a tubular wave-absorbing material layer is arranged around them, that is, the metallized holes and metallized through-holes are coaxial with the tubular wave-absorbing material l...

Abstract

The invention relates to microwave and transmission line load technology, in particular to a slope absorbing array load based on SIW loss transmission line, which is applied to X-band. Includes SIW lossy transmission lines and sloped absorbing arrays. The present invention is based on the SIW transmission line, and by setting a tubular wave-absorbing material layer around the SIW transmission line and the metallized holes and metallized through-holes on the inclined plane to absorb the array load, the wave-absorbing effect in the X-band is good, and the return loss is less than -29dB. Easy to integrate and miniaturize; can be applied to absorbing load of SIW device test fixture calibrator or ring isolator.

Description

technical field [0001] The invention relates to microwave and transmission line load technology, in particular to a slope absorbing array load based on SIW loss transmission line, which is applied to X-band. [0002] technical background [0003] In recent years, transmission line technology has developed greatly. The traditional waveguide is an earlier transmission line used in the microwave field. It has a large power capacity and low loss, but it is large in size and difficult to integrate and miniaturize. With the development of microwave integrated circuits, striplines, microstrip lines and Microstrip structures such as slot lines, these structures are easy to integrate and miniaturize, and better meet the needs of the development of microwave integrated circuits, but the loss of microstrip structures is relatively large. [0004] Substrate Integrated Waveguide (SIW) is a new type of transmission line that can be integrated on a dielectric substrate. SIW usually punche...
