본 발명은 도 1에 보인 바와 같은 무선 공중파(RF) 전력 에너지를 안테나를 통해 공중으로 방사하고 그 전자기파를 수신하여 전력변환을 수행하여 수신단의 응 용회로에 전원을 공급할 수 있는 무선 전력 전송 시스템(이하 무선 전력 전송 시스템)에 있어서 수신단의 전원 공급 장치로서의 안테나 일체형 IC칩(이하 무선 전원 IC칩)에 관한 것이다. The present invention is a wireless over-the-air (RF) electrical energy to the wireless power transmission system in which the radiation into the air through an antenna, and receives the electromagnetic wave to perform the power conversion to supply power to the response circuit of the receiving end as shown in 1 ( in the following a wireless power transmission system) related to an antenna-integrated IC chip as the power supply of the receiver (the wireless power IC chip). 수신단에서 전자기파 전력을 수신 변환하면 수신단의 응용회로에 전원을 공급할 수 있다. When receiving the electromagnetic wave power conversion at the receiving end it is possible to supply power to the application circuit of the receiver.

이와 같이 전원 공급선을 사용하지 않는 무선 전력 전송 기술은 크게 두 가지로 분류할 수 있다. Thus, the wireless power transmission techniques that do not use the power source supply lines can be broadly classified into two categories. 하나는 유도 코일 방식이며, 따른 하나는 공기 중을 통하는 전자기파 송수신에 의한 전력 에너지 전송 방식이다. One is an induction coil type, and one is the power energy transmission system by transmitting and receiving electromagnetic waves in the air passing through in accordance with.

첫 번째 방식인 코일을 이용하는 전자기 유도 결합 방식은 접촉 없이 무선으로 전력을 전송할 수 있으나 수신단 구조의 크기 및 전송 거리가 30cm 이내로 짧다는 단점을 갖는다. The first method is an electromagnetic induction coil coupled using a method to transfer power wirelessly, without contact but has the disadvantage that the size and the transmission distance of the receiver structure is short within 30cm. 두 번째 방식의 전자기파를 이용한 전력 에너지 무선 전송 방식은 수 km의 원거리에서도 전력 송수신을 할 수 있다는 장점을 갖지만 전력 변환 효율이 낮고 높은 전력을 송신하는 경우에는 인체에 미칠 전자기파의 유해성에 대한 전파전계 강도에 대한 제한 규약을 갖고 있어 주로 인공위성에서 태양 전지로 전기를 발생 저장한 후 마이크로파를 이용해 무인도나 사람의 인체 유해성이 없는 곳에서 전기를 수집하여 전기 에너지를 공급하려는 대형 및 대전력 에너지 공급 시스템 사업에 관련된 것이 대부분이었다. In either case, it is transmitting a high power electric energy wireless transmission system using electromagnetic waves of the second approach has the advantage of being able to power transmission in a number of km distant low power conversion efficiency, the electric wave field strength of the hazards of the electromagnetic waves have on the human body to have had a limited contract for large and high-power energy supply system business, mainly to Save generate electricity from artificial satellites to solar cells using a microwave supplying electrical energy by collecting the electricity where there is no human body hazard a deserted island or a person it was the most relevant.

그러나 근래에는 휴대폰이나 멀티미디어 플레이어, 노트북 등 많은 휴대기기들과 유비쿼터스 센서 네트워크의 각종 센서기기, 홈 네트워크의 각종 클라이언트 기기들이 전력 공급선 없이 이동성 및 편리성을 강조한 휴대용으로 사용될 필요성이 크게 대두되고 있다. However, recently, there is a need to be used as a mobile phone or multimedia player, a portable laptop and many mobile devices and various types of sensor devices, the various client devices in the home network of the ubiquitous sensor networks emphasizes the portability and convenience of the power supply line without being largely soy. 충전 건전지 기술의 발달로 어느 정도는 휴대성 및 이동성 의 편리함을 확보하였기만 여전히 충전기를 통해 충전을 하여야 하며, 휴대하여 기기를 사용하는 시간의 제약을 받는다. With the development of rechargeable battery technology to some extent are to be charged through only hayeotgi ensure the convenience of portability and mobility still charger, given the constraints for the time that a mobile using the device.

본 발명은 위에서 언급한 두 번째 방식의 전자기파 전력 에너지 전송 방식으로시 특정 주파수를 갖는 전자기파(RF파 또는 마이크로파, 혹은 밀리미터파)를 이용한 원거리에서의 전력 에너지 무선 송수신 시스템에서의 수신단 전력 에너지 수신 변환장치로서의 안테나 일체형 수신 전력 변환 IC칩 구조에 관한 것이다. The present invention is an electromagnetic wave having a specific frequency when in a second way electromagnetic electric energy transfer system of the above mentioned (RF wave or a microwave, or a millimeter wave), for receiving the receiver power energy in the electric energy wireless transmission and reception system in the far by converter as relates to an integrated antenna receive power conversion IC chip structure. 이를 통해 미소한 전력 에너지를 전자기파를 통해 수신하여 충전 변환함으로써 수신단의 전원 공급 장치로서 사용하는 수신 안테나를 포함하는 전력 변환 단일 IC칩인 무선 전원 IC칩 구조에 관한 것이다. This minute by a power received through an electric energy by converting an electromagnetic wave to charge a receiving antenna to be used as the power supply of the receiving end through conversion relates to a single IC chip, a wireless chip power IC structure.

종래의 관련 기술들은 송신된 전자기파를 수신하는 안테나와 PCB에 제작된 수신 전력 변환 회로 장치들이 단일 칩 형태의 일체형이 아니라 분리되어 있어 안테나와 전력 변환 모듈(IC칩이거나 PCB 기판에 구현된 RF 칩 모듈) 중간에 안테나와의 임피던스 매칭 회로를 삽입 구성해야 하는 기술적 어려움과 번거로움이 있고, 그 수신단의 크기에 있어 차지하는 공간이 커서 휴대용 전자기기 등에 간단히 삽입 연결하여 전원 장치로 사용하기가 어렵다는 단점을 가지고 있다. Conventional technologies have the received power conversion circuit devices it is separated as a piece of a single chip type or antenna and the power conversion module (IC chip, the RF chip module implemented on a PCB substrate manufactured to the antenna and the PCB for receiving the transmitted electromagnetic waves ) and the hassle and technical difficulties that need to be configured inserting the impedance matching circuit with a medium antenna, with the difficulty disadvantages that the space occupied in the size of the receiver cursor by simply connecting it to insert a portable electronic device used as a power supply have. 이러한 제약들로 인해 전자기파를 이용한 무선 전력 전송 송수신 장치는 실험실 등에서 주로 실험용으로 구현되어 이루어졌으며 상용화되어 판매되어지는 무선 전원 IC칩 형태는 없었다. Transmitting and receiving wireless power transmission apparatus using an electromagnetic wave due to these constraints are commercially available were made mainly implemented in the experimental laboratory, etc. There was no wireless power IC chip type that is free. 또한 이러한 단점을 갖는 수신단은 충전기를 충전하기 위한 장치로서만 활용되었다. In addition, a receiver having such a drawback has been used only as a device for charging the charger.

상기와 같은 문제점들을 해결하여 휴대기기들의 휴대성을 극대화하고 무선 전력 전송이라는 전력산업의 새로운 수익 모델을 창출 구현하기 위해 원거리 무선 전력 전송 시스템에서 수신단의 전자 및 전기 기기의 상시 전원 공급 장치 및 충전을 위한 전원 공급 장치로서의 안테나 일체형 단일 ASIC칩 구조 형태의 무선 전원 IC칩 형태(베어 칩) 및 패키징된 모듈 형태(무선 전원 IC칩을 내장하고 패키징된 개별 IC 부품)로 제공하고자 한다. Solve the above problems by the regular power supply and charging of the electronic and electrical devices of a receiver in a remote wireless power transmission system to implement maximize the portability of a mobile device and generate new revenue model of the electric power industry of wireless power transmission for single ASIC chip integrated antenna structure in the form of a wireless power IC chip form (bare chip), and the packaged module form as a power supply and to provide a (built-in wireless IC chip and power source packaged individual IC part).
