Eachof the system is include of three section, tag, reader and host computer that tag’s antenna is necessary to identified by readers. In this paper, new design of a dipole antenna with rectangular fractal shape radiator element with two frequency range including Ultra High Frequency (UHF) band and microwave band has been obtained that using measured return loss bandwidth, also it can be simulated impedance bandwidth. The simulations show radiation pattern of the antenna is cover the entire frequency range including UHF and microwave  band.
