Sensors that are buried inside concrete for various data collection purposes are usually powered with batteries or wires. The concept of wireless powering arises from the fact that sensors could also be powered from the power delivered to the load resistance of the antenna. The antenna used in this paper is the Sierpinski Gasket Antenna (inside concrete) has to absorb power from the plane wave incident on concrete. A fractal surface has a larger surface area means that the fractal antenna is an ideal choice to power a sensor inside concrete since the surface area is much larger. Concrete was modeled in HFSS according to the parameters in previous research papers.
