DESCRIPTION:[]Title: Multiport Rectenna Design for Ambient RF Energy Harves
 ting\n\nAbstract: The Internet-of-Things (IoT) is predicted to bring a rev
 olution in the way we monitor our health\, environment\, and infrastructur
 e and allow enhancements in efficiency\, performance\, and services. Howev
 er\, a critical issue is how to power IoT devices as they become more nume
 rous and smaller. Ambient RF energy harvesting\, which utilizes rectifying
  antenna (rectenna) to extract energy from the environment by leveraging R
 F signals radiated by communication infrastructure\, such as WiFi\, cellul
 ar\, and broadcast systems\, is a promising technology to overcome the iss
 ue of energizing massive IoT devices. A key problem in ambient RF energy h
 arvesting is that the extremely low RF power density of the ambient RF env
 ironment significantly limits the available output dc power. In this talk\
 , the state-of-the-art multiport rectenna technology for overcoming the lo
 w output dc power challenge of ambient RF energy harvesting will be presen
 ted. Different techniques to suppress the mutual coupling which degrades t
 he multiport rectennas will be highlighted. In addition\, the multi-band\,
  multi-polarized\, and multiport rectenna design technology\, which jointl
 y exploits frequency domain\, polarization diversity\, and spatial domain 
 to significantly enhance the output dc power\, will be introduced. Further
 more\, transparent multiport rectenna design integrated with solar cell\, 
 which supports hybrid solar and RF energy harvesting\, will be provided.\n
