드론은 다양한 산업 분야에서 매력적이었지만 배터리의 제한된 전력 공급으로 인해 드론을 장시간 작동하는 데 어려움이 있었습니다. 마이크로파 전력 전송(MPT)은 이러한 한계를 해소할 수 있는 가장 유망한 기술 중 하나입니다. 여러 종류의 드론 중 마이크로 드론의 비행 가능 시간이 더 짧기 때문에 MPT 시스템을 갖춘 무선 충전 액세스가 가능한 마이크로 드론을 제공하는 것이 합리적입니다. 그러나 이전 연구에서는 마이크로 드론 충전 애플리케이션에 적합한 렉테나가 없습니다. 본 논문에서는 20W급 출력을 갖는 가볍고 컴팩트한 렉테나 어레이가 개발된 C밴드에서 마이크로 드론용 MPT 시스템을 제안하였다. 203mW/cm의 플랫탑 빔 조명 아래2 16개 소자 렉테나 어레이의 전력 밀도를 측정했습니다. 16소자 렉테나는 경량화를 위한 벌집형 기판과 고출력을 위한 GaAs 쇼트키 배리어 다이오드를 사용하여 형성되었습니다. 무게는 37.5g, 크기는 146.4mm x 146.4mm였다. 주입 잠금 마그네트론에 의해 27.0W의 무선 주파수 전력이 생성되고 송신 위상 배열에서 19.0W가 전송될 때 5.8GHz에서 280V에서 134W의 DC 전력을 출력했습니다. 중량 대비 출력비는 0.72W/g이었다. 전력변환효율은 61.9%였다. 이 수치는 이전 연구의 렉테나보다 성능이 뛰어나며 마이크로 드론에 대한 MPT 시스템에 적합합니다.

Abstract: Drones have been attractive for many kinds of industries, but limited power supply from batteries has impeded drones from being operated for longer hours. Microwave power transmission (MPT) is one of the most prospective technologies to release them from the limitation. Since, among several types of drones, micro-drone has shorter available flight time, it is reasonable to provide micro-drone with wireless charging access with an MPT system. However, there is no suitable rectenna for micro-drone charging applications in preceding studies. In this paper, an MPT system for micro-drone was proposed at C-band where a lightweight and compact rectenna array with 20-W class output power was developed. Under illumination of a flat-top beam with 203 mW/cm2 of power density, a 16-element rectenna array was measured. The 16-element rectenna was formed with the aid of a honeycomb substrate for lightness and GaAs Schottky barrier diodes for high output. It was 37.5 g in weight and 146.4 mm by 146.4 mm in size. It output 27.0 W of dc power at 19.0 V at 5.8 GHz when radio frequency power of 280 W was generated by the injection-locked magnetron and 134 W was transmitted from the transmitting phased array. The power-to-weight ratio was 0.72W/g. The power conversion efficiency was 61.9%. These numbers outperformed the rectennas in the preceding studies and are suitable for an MPT system to micro-drone.
