This paper presents two transmitter architectures for wireless power transmission (WPT) applications. These architectures aim at transmitting high peak-to-average power ratio (PAPR) multi-sine signals, which have demonstrated to improve the RF-dc conversion efficiency of rectifier circuits, such as the ones in the receiving end of a WPT system. In order to overcome the challenges associated to the...
A novel active antenna array, based on substrate integrated waveguide technology, is designed and demonstrated. The array is based on cavity-backed antenna oscillators, and the coupling is obtained by properly connecting the cavities. Accurate control of both amplitude and phase of the coupling is achieved. The most significant result of this novel array is the possibility to obtain beam-scanning...
