Abstract New design of a dipole antenna with rectangular fractal shape radiator element with two operating bands for radio frequency identification (RFID) is presented. By using fractal shape slot and metal meander patch, the proposed antenna has the wide and dual measured return loss bandwidth. Besides, the omnidirectional radiation pattern of the design antenna cover the entire frequency range including ultra high frequency (UHF, 860–960 MHz) band and microwave (2.45 GHz) band has been obtained. Several properties of the proposed antenna for dual‐band operation such as impedance bandwidth, radiation pattern, and measured gain have been investigated numerically and experimentally in detail. © 2008 Wiley Periodicals, Inc.
