Multiband Fractal Microstrip Patch Antenna for Wireless Applications
Multiband wang-shaped fractal antenna is obtained by applying fractal geometry. Initially a rectangular patch is taken and fractal geometry is applied. Two iterations of fractal geometry are applied to form double wang-shaped fractal antenna. Best characteristics were obtained using slot cut DGS in which seven rectangular slots have been cut out. This antenna resonates at 3.7GHz, 4.6GHz, 5GHz and 7.6GHz with return loss of -20.75dB, -18.3dB, -21.1dB and -27.3dB, gain of 0.7dBi, 2.36dBi, 4.13dBi and 2.63dBi and bandwidth of 200MHz, 300MHz and 900MHz at 3.7GHz, 4.6GHz, 5GHz and 7.7GHz.
