Design and analysis of reconfigurable antenna using RF MEMS and fractal geometry

Abstract

RF MEMS technology offers superior performance and has edge over the conventional solid state devices. The reconfigurability aspect in an antenna system is a desired characteristic and has been the focus area of research in recent years. The performance of reconfigurable antenna can be improved by optimization of the location of the switches and also by identifying the suitable material of RF MEMS structure. The design of Reconfigurable Micro strip Antenna using Koch fractal geometry is analysed in this paper. The simulation of design is carried out using HFSS. The fractal Antenna can provide Multiband and Wideband operation but the reconfiguration aspect can further help to improve the performance of antenna. This antenna design can support the bands of several applications including WiFi, 3G, WiMax as well as UWB range.
