Patent ID: 11916309
Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 4:
5. A magnetic field transceiver in a magnetic field communication system, the magnetic field transceiver comprising:
a controller configured to generate communication signals;
matching units configured to receive the communication signals, the matching units respectively corresponding to different matching frequencies; and
loop antennas configured to convert communication signals according to the different matching frequencies into magnetic transmission signals in a form of magnetic field energy and to transmit the magnetic transmission signals, the loop antennas being respectively connected to the matching units, wherein each of the loop antennas has a number of turns equal to: number of turns needed to generate a desired magnetic field/number of loop antennas,
wherein the matching units comprising a first matching unit, a second matching unit and an N matching unit,
wherein the loop antennas are vertically arranged based on a direction in which another magnetic field transceiver is located, and is configured to generate a magnetic field passing the loop antenna connected to the first matching unit to the loop antenna connected to the second matching unit to the loop antenna connected to the N matching unit based on the communication signals and to transfer the magnetic transmission signals to the other magnetic field transceiver.
