Study of a novel compact rectenna for wireless energy harvesting

A compact novel topology rectenna system is presented. The proposed rectenna is developed by decomposition a rectenna topology into two function parts, and then re-combination the two parts into a new topology to reach a very compact system size. The operation mechanism of the proposed novel topology rectenna is explained and analyzed. In addition, the proposed architecture is uni-planar, robust and compact, which lead to an easy design and realization at the required frequency ranges with a very low cost. A 2.45 GHz rectenna system is designed and measured to show their microwave performances.
