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

Claim 5:
6. A method of transmitting a magnetic field signal, the method comprising:
inputting communication signals to matching units respectively corresponding to different matching frequencies; and
converting, using a plurality of loop antennas respectively connected to the matching units, communication signals according to the different matching frequencies into magnetic transmission signals in a form of magnetic field energy and transmitting the magnetic transmission signals, 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 horizontally arranged based on a direction in which another magnetic field transceiver is located, and
wherein the converting comprises converting the communication signals into magnetic transmission signals in a form of magnetic field energy which is transmitted to another magnetic field transceiver by sequentially passing through 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.
