Performance analysis of Reconfigurable U- slot Fractal Antenna for Wireless applications

Rapid growth in the High density networks and advancements in the antenna technology have led to the antenna design with smaller size, lighter weight, lower cost, reconfigurable , multi band & wide band nature. However, all these advances also come with increased complexity. The lower insertion loss , excellent isolation & linearity of the RF MEMS switches serves to replace the semiconductor PIN diode and other RF switches in the reconfigurable antenna design. In this paper Reconfigurable U-slot Fractal Koch curve Micro strip Reconfigurable antenna is designed. The testing of Antenna is performed in 1 to 6 GHz frequency range. The measured & simulated results are demonstrating the Multi Band and Wide band Characteristics which is the major requirement of High density Wireless network. The design considerations of the RFMEMS switch suitable for reconfigurable Micro strip patch antennas are also discussed in this paper.
