The concept of wireless power transmission may be dated back several years ago. However, because of its limited application, it has not been fully developed until recently when theories on power transfer came up. There are increasing number of available published documents today regarding this topic. If this could be implemented on a large scale, an almost infinite amount of energy may be harnessed from a distant source such as the sun. This thesis serves specifically to eliminate the use transmission lines in order to power up certain devices (i.e. motors, Walkman's, LED, etc.) and to introduce the concept of wireless power transmission. This system will consist of a microwave transmitter and receiver plus the device it has to power up. A magnetron taken from a microwave oven will serve as the source of the microwave signal transmitted through space. It will transmit microwave signals with a frequency of 2.45 GHz which in turn the receiver will accept and turn the signal to DC. The system's receiver will be a high gain antenna capable of accepting the signals being sent by the transmitter. The microwave signal will be received by the antenna and then rectified by mixing diodes connected in parallel to the terminals of the antenna and the load (device). The rectified signal will then serve as the power source for the device to operate.
