Abstract: A dual-band planar rectenna, consisting of a modified quadrilateral square slot antenna with rectangular microstrip patch connect to a 50 Ω feed line to improve the impedance matching and a single-series diode configuration-based half-wave rectifying circuit for high conversion efficiency, operate in frequency bands of universal mobile telecommunication service UMTS (2.1 GHz) and higher WLAN/Wi-Fi (5 GHz), is proposed for RF energy harvesting and wireless power transmission. The inverted L-section transmission line is introduced between the diode and dc pass filter to eliminate the harmonics within the operating frequencies. The antenna is connected to the rectifying circuit by using a pair of 50 Ω SMA coaxial connectors. The peak measured conversion efficiency of proposed rectenna is 59.4% achieved at the input power of −9.8 dBm and optimized load resistance of 560 Ω, respectively. © Springer Nature Singapore Pte Ltd 2020.
