Gain and Bandwidth Enhancement of Sierpinski Carpet Based Fractal Patch Antenna Using Stacked Configuration

One of patch antenna biggest weaknesses is its narrow bandwidth. By integrating the effects of fractal designs, this study shows how a parasitic, a double stacked structure may be used to produce a microstrip patch antenna with a wide bandwidth and high gain. The overall bandwidth of the proposed stacked antenna design for wideband applications is 750MHz at S11 -10dB. The Self-like square carpet fractal is used to minimize antenna size. Because of the space –filling property of fractal the antenna resonance frequency goes on reducing. According to experimental results, the resonance frequency of this patch antenna drops as iteration and iteration factors increase. With a size reduction of 70.1%, wideband functionality is realized. The proposed antenna has an 8.5dB gain. The proposed antenna is appropriate for wideband applications due to its broad and greater gain features.
