  • In this paper, a new broadband rectenna is presented for the wireless transmission of microwave power. The new broadband rectenna element is based on a new printed monopole broadband antenna with size reduction using surface current distribution and a new broadband stub bandpass filter with suppression of second harmonics. A RF-to-DC conversion efficiency of 80% using a 270 ohm load resistor is obtain at 2.45 GHz. Also, a conversion efficiency of above 50 % is maintained from 1.8 GHz to 2.8 GHz.

  • This paper proposes the effective design procedure for a broadband, double-ridged horn antenna for evaluating the performance of the RF energy harvesting system with a multi-band rectenna. Using multi-mode network analysis, the higher-mode scattering parameters of the transition and horn were acquired and applied to the antenna design, respectively. As a result, the computing time could be reduced and the calculated VSWR(voltage standing wave ratio) of the antenna was very similar to the analyzed result using fully electromagnetic simulation. And there was also good agreement between the simulated and measured results. The designed broadband antenna has a bandwidth of 660~6360 MHz and 6~13.7 dBi peak radiation gain.
