Circular and elliptical shaped fractal patch antennas for multiple applications

Abstract

In this paper fractal concept is applied to the antenna patch. Two antennas are designed of circular and elliptical shaped fractal patch.Antennas aredeigned and simulated up to iteration-3 in CST software. The designedcircular fractal antenna resonates in 1GHz to 12 GHz frequency bands and provides good gain at resonating frequencies. Ellipse shaped fractal antenna resonates in frequency band of 1GHz to 12GHz. Good bandwidth and positive gain is achieved. The designed antennas have multiple applications in bands of 1GHz to 12 GHz like2.4 GHz for Wi-Fi, 4-6 GHz band frequency for C band applications and 8-12 GHZ forradar, satellite communication and wireless computer networks.The designed antennas are fabricated and tested using microwave vector network analyzer (VNA). Measured and simulated results are compared.
