Abstract
A 2.45 GHz industrial, scientific and medical band rectenna with a two-layered structure for various applications involving microwave wireless power transmission (WPT) has been designed and measured in this article. A microstrip antenna with two perfect electrical conductor walls loaded for gain enhancement is designed. In addition, a typical single-diode compact radio frequency (RF) rectifier with a series bandpass structure is presented. The simulated RF to dc conversion efficiency of the rectifier is above 50% when the input power ranges from 0 to 28 dBm. The fabricated rectenna is compact with a dimension of 0.5λ × 0.5λ. A RF to dc conversion efficiency of about 73% is achieved under received power density of 38.5 W/m2 with a 500 Ω dc load. Due to the integration design of antenna and rectifier, the proposed rectenna is suitable to be well applied in miniaturization of rectenna array.
