Proximity sensor assembly and inspection system

摘要

A proximity sensor assembly with a sensing element having a substrate and an antenna pattern disposed on one or more planar surfaces of the substrate is disclosed. The cable is fed substantially parallel to the planar surfaces of the substrate and is attached to the side surface of the substrate, such that the cable is oriented substantially perpendicular to the direction of the electromagnetic field emitted from the sensing element.

主权项

1. A proximity sensor assembly comprising:
a substrate comprising a first planar surface disposed in a first plane, a second planar surface disposed in a second plane, and a side surface, wherein the second planar surface of the substrate is substantially opposite the first planar surface of the substrate, and wherein the first plane is parallel to the second plane; an antenna pattern disposed on the first planar surface and/or the second planar surface of the substrate; a cable comprising a center conductor and a shield, wherein the cable is connected to the side surface of the substrate and is disposed in a third plane substantially parallel to the first plane and the second plane; a first conductive path in the substrate connecting the center conductor of the cable to the antenna pattern; and a second conductive path in the substrate connecting the shield of the cable to the antenna pattern.
