Abstract :
High PAPR signals such as multisines have been used to increase the RF-DC conversion efficiency in WPT systems. Considerable work has been dedicated to the receiver side, namely to investigate the efficiency enhancement in RF-DC converters excited with such signals. However, less attention has been paid to the transmitter side. In this paper, we propose the use of spatial power combining technique for use in WPT, to efficiently generate/radiate a high PAPR multisine signal.
