HIGH POWER RECTENNA ARRAY

A wireless power rectifying system includes, in part, a multitude of boards. Each board includes an array of antenna elements and an array of rectifying circuits each associated with a different one of the array of antenna elements. Each rectifying circuit is adapted to convert an RF signal received by the associated antenna element array to DC voltage. The spacing between each pair of adjacent boards is in a range defined by λ/20 to λ/2, where λ is the wavelength of the received RF signal.
