Description

technical field [0001] The invention relates to the field of microwave wireless energy transmission, in particular to a compact wide power input dual-polarized rectifying antenna. Background technique [0002] Microwave wireless power transmission (MPT: Microwave Power Transmission) technology converts DC energy into radio frequency energy, emits it through electromagnetic radiation, propagates in free space without physical wires, and converts it into The technology used in the DC power supply stage. Compared with wired energy transmission, wireless energy transmission has obvious advantages in terms of space flexibility, erection physical cost, and degree of freedom. It is especially irreplaceable in application scenarios such as power supply for medical sensors in the body and power supply for IoT sensor network nodes. In the 1850s, MPT technology was first used in the application research of high power, space power transmission, and remote driving of unmanned aerial veh...
