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.
The key component of a WPT system is called rectenna
The beam itself terminates on a receiver called a rectenna
, with peak intensity in its center and tapering to nearly nothing at the periphery.
The drawback of LEO system is that it can deliver power only to the rectenna
sited in the equatorial region.
TU3A-4: A Conformal 10 GHz Rectenna
for Wireless Powering of Piezoelectric Sensor Electronics
converted microwave power into electricity, allowing the helicopter to fly.
In 2015, Cola and his team were the first to overcome more than 40 years of research challenges to create a device called an optical rectenna
, which turns light into direct current more efficiently than today's technology.
TEHRAN (FNA)- Using nanometer-scale components, researchers demonstrated the first optical rectenna
, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
Moreover, a rectenna
is one important component in wireless power transmission and has been used to provide DC power in wireless sensors [2-4].
Scavenging ambient Wi-Fi transmission through the rectenna
model can be a possible solution to prolong the battery life of the active RFID tag.
Yang-Ha-Park  and Dong-Gi-Youn designed and manufactured microstrip patch dipole and Yagi-Uda antennas mainly used in the existing rectenna
and then analyzed the RF-DC conversion efficiency of wireless power transmission.
