In this paper a novel frequency reconfigurable CPW fed H-shaped patch antenna is designed. The basic antenna consists of CPW fed two H-shaped patches which operates at 2.48GHz. The basic antenna is suitable for IEEE 802.11 b WLAN (2.4GHz - 2,484GHz) application. The reconfigurability in frequency is obtained by connecting two switches in basic antenna by use of MEMS. By controlling the switches the antenna can be operated at three different frequencies namely 4.39GHz, 12.84GHz and 12.58GHz. The effect of antenna length, size, substrate, thickness, shape has been evaluated and obtained good and acceptable 2D Radiation Pattern in elevation plane, gain, and efficiency. The proposed antenna is described and simulated results are illustrated using Method of Moments based IE3D commercial software.
