Abstract
The beaming efficiency of a radiative wireless power transfer (WPT) system based on 1-D frequency-scanned antennas, to power a low-energy wireless sensor network (WSN), is studied in this work. The study is focused on the 16 frequency channels of the Zigbee protocol in the 2.45 GHz band. The beaming efficiency is analysed for different antenna lengths and number of frequency Zigbee channels, showing that using longer, more directive antennas, the coverage for the WSN can be improved, but more frequency channels are needed to achieve the same beaming efficiency than using shorter antennas, which increases the system complexity.
