Abstract

In this paper, we propose an efficient rectenna design for Bluetooth low energy (BLE) applications targeting the 2.4 GHz ISM band. A miniature meandered planar Inverted-F antenna (MIFA) was designed, simulated, fabricated, and measured,
achieving good matching with small profile. In addition, a single diode rectifier circuit was optimized at -20 dBm input power to convert the radio frequency (RF) energy captured by the antenna into DC power. Simulation results for the rectifier circuit show that it maintains a high RF-to-DC conversion efficiency. Using ideal components, an efficiency of 36% can be achieved at -20 dBm input power. When the non-idealities are considered in the rectifier, an efficiency of 20% at -20 dBm input power can be obtained.
