Drones need a constant power supply for their long-term flight. In this work, microwave power transfer (MPT) to a mini-drone X400W by DBPOWER® is proposed. The rectennas on the drone need to be illuminated uniformly by an RF power of 32.6 W. For this aim, flat-topped beams were employed at an operation frequency of 5.74 GHz. The transmission efficiency and the beam patterns were calculated between a 16-by-16-element transmitting antenna (Tx) and a 4-by-4-element receiving antenna. The transmission efficiency of 56.5 % and the average power density of 159 mW/cm2 were obtained on the receiving plane 0.8 m away from Tx. |
