This paper describes the design of a small-scale system for demonstrating retrodirective wireless power transmission. A solid-state phased array transmitter with retrodirective control drives two 5.8 GHz circular-polarized (CP) transmit antenna subarrays that illuminate a remote CP rectenna array. The total power transmitted is about 40 W. A 2.9 GHz pilot beam projected from the rectenna site is received at the transmit site and processed for retrodirective control of the 5.8 GHz transmitter.
