Design, Simulation and Comparative Analysis of Wideband & Multiband Fractal Antenna for 5G and Wireless Application

In this paper, a multiband and wideband of fractal antenna has been proposed for wireless communication applications. The Sierpinski carpet geometry has been applied to design the antenna up to third iteration. The multi frequency characteristics of the Sierpinski Carpet are characterized by its successive iterations. The proposed antenna is designed at 1.8GHz on FR-4 epoxy substrate having dielectric constant 4.4 and dimensions 60x50x1.6 mm3. The performance of the antenna has been analyzed in terms of return loss, gain, VSWR, bandwidth and efficiency with the operating frequency ranges between 1 to 10GHz. The simulation results obtain from the third iteration resonates with different frequency range of 3.4GHz, 4.8GHz, 7.7GHz, 8.6GHz, 9.4GHz and 9.7GHz with bandwidth of 98MHz, 148MHz, 344MHz, 152MHz, 678MHz and 678MHz respectively. These antennas have good antenna gains such as - 0.17dB, 4.89dB, 0.68dB, 5.66dB, 4.9dB, 4.9dB at corresponding frequencies. These resonance frequencies are able to operate for WLAN, RMM, Wi-Fi, UWB, LLWS, Wi-MAX, NAVAID, Satellite and Radar applications.
