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. 수신단에서 전자기파 전력을 수신 변환하면 수신단의 응용회로에 전원을 공급할 수 있다.The present invention relates to a wireless power transmission system capable of supplying power to an application circuit of a receiver by radiating wireless air power (RF) power energy to the air through an antenna as shown in FIG. The present invention relates to an integrated antenna IC chip (hereinafter referred to as a wireless power supply IC chip) as a power supply device of a receiving end in a wireless power transmission system). When the receiver receives and converts electromagnetic wave power, 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. 하나는 유도 코일 방식이며, 따른 하나는 공기 중을 통하는 전자기파 송수신에 의한 전력 에너지 전송 방식이다.As such, wireless power transmission technology that does not use a power supply line can be classified into two types. One is an induction coil method, and the other is a power energy transmission method by transmitting and receiving electromagnetic waves through air.

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. 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.The first method, the electromagnetic inductive coupling method using the coil, can transmit power wirelessly without contact, but has a disadvantage that the size and transmission distance of the receiver structure are short within 30 cm. The second type of energy energy transmission using electromagnetic waves has the advantage of being able to transmit and receive power at a distance of several kilometers, but the electric field strength for the harmfulness of electromagnetic waves on the human body when the power conversion efficiency is low and high power is transmitted. It has restrictions on large-scale and large-power energy supply systems that want to generate electricity from satellites and store electricity from solar cells, and then use microwaves to collect electricity on uninhabited islands or in places where there are no human health hazards. Most involved.

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. 충전 건전지 기술의 발달로 어느 정도는 휴대성 및 이동성 의 편리함을 확보하였기만 여전히 충전기를 통해 충전을 하여야 하며, 휴대하여 기기를 사용하는 시간의 제약을 받는다.However, in recent years, many portable devices such as mobile phones, multimedia players, and laptops, various sensor devices of ubiquitous sensor networks, and various client devices of home networks have been required to be used as portable devices that emphasize mobility and convenience without power supply lines. Although the development of rechargeable battery technology has secured the convenience of portability and mobility to some extent, it still needs to be charged through a charger and is limited by the time it takes to use 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. 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.The present invention is a receiver of the power energy receiving conversion apparatus in a wireless power transmission system for transmitting and receiving a long distance using electromagnetic waves (RF wave, microwave, or millimeter wave) having a specific frequency as the electromagnetic wave power energy transmission method of the second method mentioned above. The present invention relates to an antenna integrated reception power conversion IC chip structure. The present invention relates to a structure of a wireless power supply IC chip, which is a power conversion single IC chip including a receiving antenna used as a power supply device of a receiving end by charging and converting minute power energy through electromagnetic waves.

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. 이러한 제약들로 인해 전자기파를 이용한 무선 전력 전송 송수신 장치는 실험실 등에서 주로 실험용으로 구현되어 이루어졌으며 상용화되어 판매되어지는 무선 전원 IC칩 형태는 없었다. 또한 이러한 단점을 갖는 수신단은 충전기를 충전하기 위한 장치로서만 활용되었다.The related arts of the related art are that the antenna for receiving the transmitted electromagnetic waves and the receiving power conversion circuit devices fabricated on the PCB are separated from each other, instead of a single chip type, so that the antenna and the power conversion module (IC chip or RF chip module implemented on the PCB board) are separated. ) There is a technical difficulty and troublesome to insert the impedance matching circuit with the antenna in the middle, and because the space occupied in the size of the receiver is large, it is difficult to use simply as a power supply device by simply inserting and connecting to a portable electronic device. have. Due to these limitations, the wireless power transmission and reception device using electromagnetic waves was mainly implemented for experiments in a laboratory, and there was no commercially available wireless power IC chip type. In addition, the receiving end having this disadvantage was used only as a device for charging the charger.
