Microwave wavelength range approximately 1 mm (pen cable thickness) to 30 cm (approximately 12 inches). The microwave region in the electromagnetic spectrum ranges from 0.3 cm to 300 cm. The microwave region provides information about the temperature of the object emitted by microwaves. A new proposal has made the recharge of the mobile phones is done automatically as you speak on your mobile phone! The recharge of mobile phones is independent of its manufacturer and battery. The microwave signal is transmitted from the transmitter together with the message signal using a special type of antenna called a slotted waveguide antenna at a frequency of 2.45 GHz. The microwave signal is transmitted together with the message signal using a slotted waveguide antenna. The sensor looks for the mobile signal, in addition it has a "RECTENNA". Rectena receives the transmitted power and converts the microwave power into direct current.
