Patent ID: 6867661

Claim:
A millimeter wave module comprising: a microstrip line including a substrate, a microstrip conductor formed on one surface side of the substrate, and a ground plate formed on the other surface side of the substrate; a conductive portion formed on the other surface side of the substrate and adapted for receiving a probe including a strip conductor portion extending from said microstrip conductor and having a width narrower than that of the microstrip conductor, a tapered conductor portion connecting the microstrip conductor and the strip conductor portion; and a pair of conductive pads, each of which is disposed on each side of the strip conductor portion, are connected to the ground potential of said ground plate through a via hole, and are facing only a portion of the strip conductor portion, wherein at a connection between the tapered conductor portion and the strip conductor portion, an imaginary straight line that intersects the connection and is perpendicular to the strip conductor portion extends beyond the conductive pads without intersecting with the conductive pads, and wherein the strip conductor portion and the conductive pads are adapted for receiving probes.
