| description | A composite microwave circuit module includes a multilayer dielectric substrate, upper- and lower-surface grounds, an antenna pattern, a plurality of shield via holes, and a large number of first holes. The upper- and lower-surface grounds are formed on upper and lower surfaces of the multilayer dielectric substrate, respectively, and the upper-surface ground has an opening portion for waveguide coupling. The antenna pattern is formed on an interlayer of the multilayer dielectric substrate by a high-frequency signal line in correspondence with the opening portion. The plurality of shield via holes are formed around the antenna pattern and filled with a filler material to form a pseudo waveguide structure. The first holes have cavities formed in the multilayer dielectric substrate in correspondence with the pseudo waveguide structure between the antenna pattern and the opening portion of the upper-surface substrate. A method of manufacturing this circuit module is also disclosed. |
