Fractal Reconfigurable Antenna

This paper presents the use of PN junction diode on fractal monopole antenna with microstrip line for rreconfigurable multiband antennas. The developed multiband antennas focus on the applications for Wi-Fi, cordless telephone and satellite & radar. A fractal reconfigurable antenna was designed using the known fractal geometry such as Sierpinski gasket is fed by strip line using coaxial feed. Antenna’s frequencies gets turn on and off with the position and biasing of PN diode on strip line. Simulations were done on the CST software for the analysis of reconfigurable patch antenna.
