Wireless Power Transfer: The Role of Antennas in Energy Systems By doing away with physical connectors and allowing new levels of ease, safety, and creativity across sectors, wireless power transfer, or WPT, is completely changing the way energy is provided. An essential but sometimes disregarded part of this ground-breaking technology is the antenna. Antennas are essential for effective energy transmission in WPT systems, whether they are used to power medical implants, charge electric cars, or power Internet of Things devices. Wireless power systems use antennas to send and receive electromagnetic waves, which transport energy through the atmosphere. Usually, radio frequency (RF), microwave transmission, or resonant inductive coupling are used to run these systems. For effective, targeted, and secure energy transfer at distances varying from a few millimeters to several meters, each technique depends on carefully constructed antennas. Antennas are essential for accurately directing...
