Abstract: A radio frequency (RF) weak magnetic field detection sensor includes a ferromagnetic core, a pickup coil disposed to surround the ferromagnetic core, a substrate that includes an opening, a core pad connected to the ferromagnetic core and a coil pad connected to the pickup coil, and an insulating tube interposed between the ferromagnetic core and the pickup coil. The insulating tube includes a bobbin around which the pickup coil is wound, and a core hole formed to pass through the bobbin and configured to accommodate the ferromagnetic core.

Abstract: A magnetic field communication method and apparatus using a giant magnetoimpedance (GMI) magnetometer are disclosed. The magnetic field communication apparatus includes a GMI magnetometer configured to detect a first communication signal based on a received magnetic field signal, a first signal extractor configured to extract a second communication signal comprising a message signal from the first communication signal, a second signal extractor configured to extract a third communication signal by removing a magnetization frequency signal from the second communication signal, and a third signal extractor configured to extract the message signal by removing a carrier wave frequency signal from the third communication signal.
