Used to operate small electronic devices, such as the cell phones. This work will deal with the electromagnetic signals as a renewable energy sources. An analog circuit will prepare using diodes and a charged capacitance and antenna to convert the energy of ambient E.M. waves (Radio Frequencies RF) to a D.C. voltage. The measurements will be demonstrated using different kinds of antenna. In addition, the ambient RF frequency according to Iraq/Babylon/Hilla city will be collected from the communications tower and measured using a receiver circuit.in this paper used three kinds of antenna, wire antenna, air antenna, dish antenna, Measuring the DC Power. the amount of the DC Power that obtained using a dish antenna is approximate the energy that collected using an air antenna. The amount of the DC. Power could be controlled by the charging time (RC) of the capacities.
