  • Abstract
    A novel bow-tie retrodirective rectenna designed at 5.8 GHz is proposed. The new retrodirective rectenna combines a traditional rectenna with a retrodirective array. The new retrodirective rectenna array can automatically steer its main beam towards the power source and hence is not sensitive to the power incident angle changes. It can provide a constant DC output voltage within ±10° and 90% DC output voltage within ±30°. The conversion efficiency of the arrays is 84% when the power density is 10 mW/cm2.
