The Microwave Power Transmission (MPT) is the possibility of feeding a system without contact by using microwave energy.The\nchallenge of such system is to increase the efficiency of transmitted energy from the emitter to the load. This can be achieved by\nrectifying the microwave energy using a rectenna system composed of an antenna of a significant gain associatedwith a rectifier with\na good input impedance matching. In this paper, a newmultiband antenna using the microstrip technology and fractal geometry is\ndeveloped. The fractal antenna is validated into simulation and measurement in the ISM (industrial, scientific, and medical) band\nat 2.45GHz and 5.8GHz and it presents a wide aperture angle with an acceptable gain for both bands. The final antenna is printed\nover an FR4 substrate with a dimension of 60 Ã?â?? 30mm2.These characteristics make the antenna suitable for a multiband rectenna\ncircuit use.
