An H-plane wide-angle rectenna using an in-phase/anti-phase dual-feed antenna

A new H-plane wide-angle rectenna using an inphase/anti-phase dual-feed antenna is proposed. Generally, high gain array antennas have a narrow beam width and its beam deviation from arrival waves seriously degrades the antenna gain. This is due to the phase difference of the waves received by multiple antenna elements. A magic-T used in the proposed dual-feed antenna divides the received waves into in-phase and anti-phase components, and these components are separately rectified by two diodes. As a result, wide-angle performance is obtained by combining the two rectified DC power. In this paper, a slot-T type magic-T is used to achieve an H-plane wide-angle rectenna. The basic concept of the proposed rectenna is experimentally confirmed and about two times of wider reception angle is obtained when compared to conventional rectennas using an array antenna.
