Photograph of the MSFC rectenna constructed in 1974 under test. Horn at left of picture illuminates the rectenna (white panel) with a Gaussian distribution of power. Rectified DC power is collected from rectenna in circular ring path and dissipated in resistive loads on the test panel at the right.
