The device, called the rectenna
, could use waste heat from car engines, or power sensors on space missions.
This work presented an efficient metasurface rectenna
for wireless power transfer based on the full absorption technique.
The first rectenna
, conceived also by Raytheon company, came in the early 1960s.
, sometimes known as rectifying antenna, plays the central role in converting RF power into DC power in RF energy harvesting as well as WPT system, and it has attracted significant attention in the past few years.

In general, a rectenna
consists of an Rx antenna and a rectifier and thus the Rx efficiency can be further decomposed into the antenna's Rx efficiency and rectifier's efficiency.
In all RFID strategies it is essential to properly design the antenna for power optimization purposes, but in the case of energy harvesting it could be also important as an energy source, harvesting the RF energy  (called rectenna
," they are flat antenna tuned to the 5.8GHz frequency used in the tests.
The combination of a rectifying device at the feed points of a receiving antenna is often known as a rectenna
system design in L-band (1-2 GHz) 1.3 GHz for wireless power transmission," Journal of Computational Intelligence and Electronic Systems, vol.
The key component of a WPT system is called rectenna
In this research, we mainly focused on the receiving side, including the rectenna
and boost converter, a low-power controlling board, and modification of the current wireless sensor module.
