Abstract

This paper presents a design of fractal microstrip patch antenna. Crown & Sierpienksi fractal slots by cutting different slots on rectangular microstrip antenna and experimentally studied on IE3D software. This design is achieved by cutting multi shapes in Crown & Sierpienksi fractal pattern & placing a microstrip line feed. This design has been studied in I iterations. The radiation pattern of the proposed microstrip antennas maintained because of the self-similarity and centro-symmetry of the fractal shapes. With fractal shapes patch antenna is designed on a FR4 substrate of relative permittivity of 4.4 and thickness 1.524mm and mounted above the ground plane at a height of 6 mm. Details of the measured and simulated results of the case-by-case iterations are presented & discussed.
