Abstract

<p>A cubic Yagi-Uda array antenna with high gain for 500 MHz rectenna is proposed. The proposed antenna is composed of two elements of Yagi-Uda antenna. The proposed antenna is compact and its volume is λ/3 × λ/3 × λ/3 because the Yagi-Uda antennas share a reflector and director. Performance of the proposed antenna is demonstrated and resultant gain is as high as 8.5 dBi. Finally, the proposed antenna is applied to a 500 MHz rectenna system with voltage doubler rectifiers and its performance is demonstrated experimentally.</p>
