Frequency and polarization reconfigurable fractal microstrip antenna

A compact fractal antenna which is both frequency and polarization reconfigurable is presented in this paper. The proposed paper presents a Minkowski fractal microstrip antenna loaded with slots operating at a frequency of 1.7GHz. Frequency and polarization re-configurability is achieved by introducing four slots on the fractal shaped patch with PIN didoes as switches across them. By varying the ON and OFF conditions of PIN diodes, the antenna is able to operate in 5 different frequencies and as well as for two different polarization.
