abstract
A new rectenna circuit is described. The rectenna circuit uses a bowtie antenna integrated with a diode. The newly developed bowtie rectenna has a high conversion efficiency, is broadband, is not sensitive to the angle of the incident field, has a good match to its circuit, and behaves as a lowpass filter for dc output. A microwavetodc conversion efficiency of 79% has been achieved at 2.45 GHz. 1993 John Wiley & Sons, Inc. Copyright 1993 Wiley Periodicals, Inc., A Wiley Company
