Abstract
An electrical power distribution system wherein electromagnetic energy irradiates a large spatial area is configured to include an array of antenna-rectifier modules wherein the receive aperture of each module is established in accordance with the electromagnetic field intensity at the location of that particular module so as to provide the rectifier circuitry with a predetermined amount of electrical power. Each antenna-rectifier module includes an array of high impedance (e.g., antiresonant) dipoles that are spaced apart along a two-wire transmission line. The total number of dipoles employed is established to provide the desired receive aperture and the impedance of each dipole is established so that the total impedance of the array substantially matches that of the rectifier circuitry employed. The rectifier circuitry is enclosed in and electromagnetically shielded by a conductive housing that is removably interconnected with the array of antenna elements and first and second filtering circuits are included to respectively eliminate high frequency signal components that can be coupled to and radiated by the antenna structure and high frequency ripple within the DC output signal…
