Energy-efficient Rectennas for Wireless Power Transfer and Energy Harvesting

This thesis developed efficient energy conversion modules that can harvest energy from radio waves available in the environment and convert it into electrical energy to power small electronics. The work creates new potential ways in which we can get more usable power wirelessly while maintaining radiation safety requirements, all in a small form-factor that can be embedded into mobile electronics. The long-term significance of this research is the deployment of safe, far-field wireless power transfer that will have the effect of reducing some of the harm that electronic waste from cables causes to the environment.
