Multiband fractal based reconfigurable antenna with introduction of RF MEMS switches for next generation devices

Next generation network’s main requirements are compact size and also support to heterogeneous network. Fractal antennas have useful applications in cellular telephone and microwave communications. Video conferencing, streaming video are main applications that are included in next generation networks and requirements for these applications are high data rates require to have high bandwidth. But as size of antenna reduces, bandwidth support also reduces. So it is required to have small size with high bandwidth. Fractal antennas are proposed in this paper for different applications as it is compact and also has good bandwidth. In this paper, we propose a reconfigurable fractal shape antenna for Ku and Ka band. Its performance analysis shows these antennas are multiband antennas support Ku and Ka bands and also support mobile terminal applications which are sight to be used in next generation networks. Different number of iteration is performed for its support to different bands. Re-configurability in antenna is another important concept and in this work; the reconfigurability is achieved by using radio frequency microelectromechanical system (RF MEMS) switches.
