This paper presents particle swarm optimization (PSO) method based design of a dual-band patch antenna using IE3DTM. The method effectively obtains the geometric parameters for efficient antenna performance. Maximum return loss obtained at 2.4 GHz is -43.95 dB and at 3.08 GHz is -27.4dB. Its bandwidth of 33.54 MHz ranges from 2.38355 GHz to 2.41709 GHz.
Design of low profile single feed dual band microstrip antenna operated at Wi-Fi/Wi-Max system is presented. It is demonstrated that by cutting slots into radiating edges of microstrip patch antenna, a dual frequency response is achieved. The antenna was studied by means of numerical simulation. The return losses at 2.45 GHz, 3.4 GHz are -21.5 dB, -13.2 dB respectively. Its bandwidth of 35 MHz extends...
