Magnetic field probe

摘要

A detector of a magnetic field probe includes a first wiring pattern formed on a first surface of a multilayer substrate and having a predetermined inclination with respect to an axial line direction of the magnetic field probe, a second wiring pattern formed on a second surface and having the predetermined inclination with respect to the axial line direction, and a first penetrating via penetrating through the multilayer substrate in the thickness direction and connecting a front end portion of the first wiring pattern and a front end portion of the second wiring pattern. A rear end portion of the first wiring pattern is connected to a conductor pattern configuring a strip line and a rear end portion of the second wiring pattern is connected to ground patterns configuring the strip line.

1. A magnetic field probe comprising:
a wiring substrate; a detector formed on a front end portion of the wiring substrate; and a transmission line having a conductor pattern and a ground pattern and connecting the detector and a base end portion of the wiring substrate, wherein the detector includes:
a first line wiring pattern formed on a first surface of the wiring substrate and having a predetermined inclination with respect to an axial direction of the magnetic field probe;a second line wiring pattern formed on a second surface of the wiring substrate, which opposes the first surface, and having the predetermined inclination with respect to the axial direction of the magnetic field probe; anda first via penetrating through the wiring substrate in a thickness direction and connecting a front end portion of the first line wiring pattern and a front end portion of the second line wiring pattern, a rear end portion of the first line wiring pattern being connected to the conductor pattern configuring the transmission line, and a rear end portion of the second line wiring pattern being connected to the ground pattern configuring the transmission line.
