This paper discussed the design of a dual-band harvester to efficiently handle a wide input power range while addressing the failure voltage issue in conventional rectifiers by operating a FET as a switch amongst low and high input powers. Designed f

In this paper, a rectenna is introduced by making use of an adaptive rectifier topology and a low-cost metasurface based printed antenna to cover a wide-range of input power levels. The low-cost metasurface printed antenna is based on flexible substr

In this brief, a novel methodology for estimating the initial diode bias voltage in multiport receivers was developed. We tested the methodology for four different Schottky diodes from different vendors (Win Corp, HP, Hitachi, and Siemens), but the p

In this brief, we developed a detailed Simulink model that emulates the radio frequency and digital base band of a six-port receiver. In contrast to other results published in the literature, we not only provide a controlled continuous bias to the di
