Abstract
There can be provided an LNB converter including a multilayer substrate formed of more than two layers, capable of providing adequate transit characteristic for any frequency, and a multilayer substrate. A microstrip line is provided at one surface layer's pattern and a second layer's pattern cooperating with the surface layer's pattern to sandwich a dielectric layer underlying the surface layer's pattern. A probe is inserted from the surface layer's pattern in a direction intersecting a 4-layer substrate and in at least one pattern layer other than the first and second, pattern layers at least a region surrounding a hole having a probe passing therethrough is either a pattern-free region provided by removing a predetermined region surrounding the hole or an isolated region corresponding to a predetermined region surrounding the hole and electrically isolated from an outer region of the pattern layer.
