Abstract

The invention relates to an energy and information parallel transmission rectifier antenna array, which comprises a slot-coupling corner-feeding dual-polarization microstrip antenna array and microstrip rectifier circuits. The microstrip rectifier circuits are arranged at two adjacent sides of the microstrip antenna array respectively. Energy output ports of the microstrip antenna array are connected with input ends of microstrip rectifier circuits through SMA connectors respectively. The parts above all adopt a printed circuit, and the whole body is prepared on a dielectric substrate, the twosides of which are coated with copper plates respectively. The energy and information parallel transmission rectifier antenna array adopts a non-uniform power distribution network and adopts multipleports to carry out rectification, and ensures signal transmission, and meanwhile, realizes energy transmission as much as possible to enable the rectifier circuits to have high conversion efficiencyand high output power. The rectifier antenna array can be used for the aspects of wireless energy supply of medical and urban infrastructure monitoring and military survey and the like.

Description

technical field [0001] The invention relates to the field of wireless energy transmission, in particular to a rectifying antenna array for parallel transmission of energy information. Background technique [0002] Microwave Power Transmission (MPT: Microwave Power Transmission) technology breaks the traditional mode of energy transmission through cables, and uses microwaves as carriers to transmit it wirelessly, providing a new transmission method. At the end of the 19th century, the American scientist Nikola Tesla first proposed the concept of microwave energy transmission. Modern microwave energy transmission technology began in the 1960s and was first used in high-power applications, including microwave-driven unmanned aerial vehicles, high-altitude permanent operating platforms (now near-space aerostats) power supply, complex ground environment power transmission, Solar satellite power transmission, small and medium power industrial electricity, etc. Especially with th...
