Abstract

The invention discloses an electromagnetic field energy collection device, which includes a coupler, an isolator, a rectifier unit and an energy storage unit connected in sequence, the coupler is used to receive electromagnetic field signals and convert the electromagnetic field signals into circuit signals, and the isolator is used to convert the circuit signals Transmitted to the rectifier unit and used to prevent the interference signal from the rectifier unit from being transmitted to the coupler, the rectifier unit is used to convert the circuit signal into a DC signal as DC energy, the energy storage unit is used to store the DC energy output by the rectifier unit and used for Output DC energy. The above-mentioned electromagnetic field energy harvesting device isolates the noise generated by the circuit after the isolator from the coupler by setting the isolator, so that the noise from the subsequent circuit, such as the rectifier, cannot be radiated through the coupler, avoiding damage to the nearby communication antenna. Interference, thereby ensuring the performance of the communication system. The invention also discloses a communication device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an electromagnetic field energy collection device capable of absorbing and acquiring electromagnetic field energy from the periphery of a communication antenna and a communication device. Background technique [0002] Low-power electronic devices and low-power sensing devices have a wide range of application scenarios. In many occasions, there is no power line to supply power to them, or it is inconvenient to use power lines to supply power. Therefore, battery power is a common method. But a more beneficial way is to harvest energy from the surrounding environment. Using photovoltaic cells to convert light energy into electrical energy and vibration mechanical energy into electrical energy is a method that has been studied more. Converting the electromagnetic field energy in the environment into usable electrical energy is also a method, but the difficulty lies in the fac...
