This article reports a novel broadband rectifying antenna (rectenna) using the printed monopole antenna and the band‐pass stub band‐pass filter, which is designed in the microstrip line structure at 2.45 GHz for the wireless transmission of microwave power.We suggest a novel H‐shape printed monopole antenna with size reduction of the radiator and the ground plane using surface current distribution, and a broadband stub band‐pass filter with suppression of the second harmonic. The rectifying circuit with stub filter doesn't need additional area because it is fabricated on the ground plane, which is widened to acquire broadband characteristic of the monopole antenna. The RF‐to‐DC conversion efficiency of 66% is obtained by using a load resistor of 270 Ω at 2.45 GHz. Also, the conversion efficiency is maintained from 2 GHz to 3 GHz above 50%. © 2010 Wiley Periodicals, Inc.
