Hemi-membrane substrate integrated waveguide

Abstract

The invention discloses a half-mold substrate integrated wave (HMSIW), whose two surfaces contains positive metal paster and back metal paster separately, wherein the rectangle wave (4) is composed of positive metal paste on the dielectric substrate (1), whose two ends are input port (41) and output port (42); a row of connecting metal hole (3) is set on the rectangle part of wave (4) middle segment; the metal through-hole (2) is set on four corners of dielectric substrate (1) to fix, which contains metal case in the inner wall of through-hole in connection with metal paster.

Description

technical field [0001] The invention relates to a millimeter wave and microwave waveguide structure, in particular to a half-mode substrate integrated waveguide (HMSIW). Background technique [0002] In the existing design of millimeter-wave and microwave passive devices, the rectangular waveguide has been widely used as a waveguide structure with excellent performance. avoid. The substrate-integrated waveguide (SIW) that has emerged in the past few years can be processed by a standard printed circuit board (PCB) process while maintaining the waveguide characteristics similar to the rectangular waveguide. Significant improvements have been made in size, size, and integration with planar circuits. However, the traditional substrate-integrated waveguide (SIW) has a relatively large size weakness in the lower microwave frequency band (such as X-band and Ku-band), which will lead to infinite circuit board area when designing delicate microwave circuits. This increases the siz...
