Abstract

The invention discloses a flexible antenna array based on microwave energy transmission. The flexible antenna array comprises a dielectric substrate, a patch array and an equivalent grounding plate layer. One surface of the dielectric substrate is fixedly connected with the patch array, and the other surface of the dielectric substrate is fixedly connected with the equivalent grounding plate layer. A liquid metal antenna which works at 2.45 GHZ and is used for microwave energy transmission is printed by applying a liquid metal printing technology and a flexible material. The liquid metal patch antenna gives full play to the advantages of repairability, flexibility, reconfigurability, fatigue resistance, corrosion resistance and the like of the liquid gallium indium metal and the flexible dielectric substrate, is applied to integrated small-sized electronic equipment, realizes receiving and transmitting of electromagnetic waves, is applied to long-distance energy wireless transmission, and overcomes the disadvantage of low unit energy collection and conversion efficiency of a traditional antenna.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a flexible antenna array based on microwave energy transmission. Background technique [0002] The microwave receiving antenna and rectifier circuit are important components of the microwave energy transmission system, especially as the receiving end, with high energy collection and conversion efficiency, convenient and fast laying method, easy to conform to the structure of the load equipment, and have a certain self-healing ability. The new receiving antenna has important value for the promotion and application of microwave energy transmission. Compared with the traditional reflector antenna and planar array antenna, it has stronger flexibility and is an inevitable development trend in the future. [0003] Although the existing traditional patch antennas are small in size, there are problems that the antenna device is difficult to conform to and cannot maintain stable performance after ...
