Abstract:
PURPOSE: An apparatus for transmitting and receiving energy is provided to control a resonant property without an additional circuit by controlling structural properties of components. CONSTITUTION: An energy transmitting and receiving system includes an energy transmitting device(10) and an energy receiving device(20). The energy transmitting device includes a transmission feeding cable(100), a transmission inductor(110), a transmission metal electrode(120), a transmission cavity(130), and a transmission ground rod(140). The transmission feeding cable receives an AC power source. The transmission metal electrode transmits the AC power source to a reception metal electrode by the AC flowing in the transmission inductor. The position, length, or diameter of the transmission ground rod are controlled to control a resonant frequency generated by the transmission inductor.

Abstract:
PURPOSE: An energy transmission system in a communication system and a method thereof are provided to transmit multi-energy through multi-channel communication in the communication system, thereby maximizing frequency utilization efficiency. CONSTITUTION: A reflected wave separation and path determination part(100) with respect to a radio frequency(RF) signal passes a broadband RF signal to a channel selector(200) with respect to RF reception for a demodulation process. The channel selector passes a channel selected by a user. An energy regeneration part(300) regenerates energy with respect to the RF signal reflected from the channel selector. A narrow-band RF signal which passes the channel selector is processed in a data processing part(400) in order to be utilized as a communication signal. The reflected broadband RF signal is converted into DC energy required in a receiving device.

CONSTITUTION: A transmission loop(1203) has a square structure which is similar to a resonance body. The transmission loop is placed opposite from the resonance body on a receiving side. The resonance body on a transmission side includes the resonance body(1202) for the transmission side of the square structure in an external rim(1201) and remains inside to maintain the square structure. The resonance body(1212) of a rectangular shape on the receiving side is placed in a location which is opposite to the resonance body of the transmission side. A receiving loop(1213) is placed far from the resonance body of the transmission side. A winding structure of the rectangular shape can cause a greater increase of inductance than a circular spiral shape when comparing areas.
