Post-wall waveguide : ウィキペディア英語版 | Post-wall waveguide A post-wall waveguide (also known as substrate integrated waveguide (SIW) or a laminated waveguide) is a synthetic rectangular electromagnetic waveguide formed in a dielectric substrate by densely arraying metallized posts or via-holes which connect the upper and lower metal plates of the substrate. The waveguide can be easily fabricated with low-cost and mass-production using through-hole techniques where the post walls consists of via fences. The post-wall waveguide is known to have similar guided wave and mode characteristics to the conventional rectangular waveguide with equivalent guided wavelength. For instance, the equivalent width of a rectangular waveguide compared to a SIW is described in the approximation:
where is the distance between the posts in the post wall, describes the radius, and as well as are the widths of the rectangular waveguide, resp. SIW. ==External links==
