Abstract: Dual-frequency operation of antenna has become a necessity for many applications in recent wireless communication systems, such as GPS, GSM services each operating at two different frequency bands. A new technique to achieve dual band operation from different types of microstrip antennas is presented here. An evolutionary design process using a particle swarm optimization (PSO) algorithm in conjunction with the method of moments (MoM) is employed effectively to obtain the geometric parameters of the antenna performance. In this article a PSO based on IE3D®TM method is used to design dual band inset feed microstrip antenna. Maximum return loss is obtained at 2.4GHz is -43.95dB and at 3.08GHz is -27.4dB. Its bandwidth, of 33.54MHz, ranges from 2.38355GHz to 2.41709GHz. Simulated and experimental results of the antenna are discussed.
