Abstract

The invention discloses an energy acquisition device based on multiple antennas, which comprises a plurality of energy acquisition units, and each energy acquisition unit comprises an antenna unit and an energy acquisition chip. Each antenna unit comprises a first radiating body, a second radiating body and a third radiating body which are sequentially arranged from top to bottom, wherein a first dielectric substrate is clamped between the first radiator and the second radiator, a second dielectric substrate is clamped between the second radiator and the third radiator, and the first radiator is provided with a feeding point used for electrically connecting the antenna unit with the energy acquisition chip. And the input end of each energy acquisition chip is coupled with the feeding point of the first radiator, and each energy acquisition chip is used for receiving the alternating current electric energy collected by the antenna unit so as to convert the alternating current electric energy into electric energy to be used. According to the antenna unit, the influence of concrete on the antenna is greatly reduced and the sensitivity of the energy acquisition device can be improved by connecting the plurality of energy acquisition units in series or in parallel into the system. And the energy collection efficiency of the energy collection device in the concrete is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an energy harvesting device based on multiple antennas. Background technique [0002] Reinforced concrete is widely used in various structures such as tunnels, buildings, and bridges. It is usually necessary to embed sensors with power supplies into the concrete, and use the sensors to regularly monitor the temperature, humidity, force changes, displacement and corrosion etc. [0003] However, sensors with a power supply are prone to run out of power after working for a period of time. Since they are buried in concrete, the power supply cannot be replaced. Therefore, a sensor with an energy harvesting device needs to be used, that is, the energy harvesting device and the sensor are buried in concrete, and when the sensor needs to work, the energy harvesting device is used to collect energy and supply power to the sensor. However, because the existing energy harvest...
