Fractal multiband planar antenna for wireless power transmission

In this paper we have developed and designed a low cost fractal Multi band microstrip antenna structure. This antenna is validated in the ISM (Industrial Scientific and Medical) band at 2.45 GHz and 5.8 GHz. The aim of this work is to develop an antenna which can be associated with an RF-DC rectifier to design a rectenna system for wireless power transmission “WPT”. The technique used to have a multiband structure is the fractal geometry. The final circuit is a fractal multiband antenna with 65 × 30 mm2 as dimensions.
