Bow-tie retrodirective rectenna
Electronics Letters, 2006 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.
