In this paper, the authors illustrate the possibility of recovering electrical energy by using the concept of energy harvesting from signals around i.e., to receive Radio Frequency (RF) and Microwave signals present in the atmosphere and converting these signals into DC, in order to store it or power some circuit like charging a cell phone. To implement this concept, a receiver or an antenna is required to capture RF and microwave frequencies of Wi-Fi and GSM signals in the atmosphere. Designing an antenna is the main objective in realization of wireless cellular charging device.
