AB  - Electronic device use is on the rise as more and more tasks in everyday life are conducted online. As a consequence, charging is a unique aspect of any electronic device. However, the capacity of any electronic device's battery is fixed. On the other hand, charging the unit at any time and in any place is incredibly difficult. As a result, people are having a difficult time charging their electronic devices. The goal of this project is to develop a theoretical antenna model and a circuit diagram to solve this problem. To absorb EM waves from the environment and to inclusively to charge the battery, an extra helical antenna is used. The antenna would immediately come out if the residual charge of that device is less than 20%. As Electromagnetic (EM) waves pass into the antenna's receiving circuit, a continuous magnetic field causes a small amount of voltage. This induced voltage is not enough for charging a device. This induced voltage is multiplied four times in this amplified circuit and then connected to the battery of that device. This suggested approach would minimize charging crisis by 90%. This is one of the most efficient ways to use of renewable energy.
