Millimeter wave module having probe pad structure and millimeter wave system using plurality of millimeter wave modules

摘要

A millimeter wave system includes a plurality of millimeter wave modules, each of which comprises a substrate; a microstrip conductor formed on one surface side of the substrate; a ground plate formed on the other surface side of the substrate; and conductive pads which are disposed on both sides of a strip conductor portion which extends from said microstrip conductor via a tapered portion, and which are connected to the ground potential of said ground plate through a via hole, wherein the strip conductors of this plurality of millimeter wave modules are connected to each other using conductive ribbon. Moreover, when a plurality of millimeter wave modules is connected to form a millimeter wave system, the effect produced by the interaction between the unnecessary conductive pads connected to the ground potential and the strip conductor can be reduced.
