Fractal antenna for rectenna system applications

Fractal antenna for rectenna system applications

There are several challenges in developing an antenna for rectenna systems that are need to be addressed in such as low efficiency and large size of the antenna at the lower ISM frequency band. Hence, in this work a compact size and high efficiency antenna has been developed. As a result, a microstr...
