In this paper, a novel circularly polarized rectenna using a dual-feed array antenna with inclined patches is proposed to provide a dual-axis wide-angle reception capability. A new conical and pencil dual-beam circularly polarized array antenna integrating planar magic-Ts is designed and fabricated to overcome the polarization and main-beam misalignment between the transmitting and receiving antennas. To improve the rectenna’s output power, open stub matching networks are used to achieve the matching between the antenna and rectifying diodes. Two types of circularly polarized dual-axis rectennas which respectively allow the parallel and series connections of two diodes are experimentally evaluated and compared to confirm the wide-angle reception capabilities in the x-z and y-z planes.
