Designing of Microstrip Feed Antenna by Combining Circular and Square Microstrip Antennas

This paper presents a designing of microstrip patch antenna immixing circular and square slots by cutting different slots on rectangular microstrip patch antenna and experimentally studied on IE3D software. This design is achieved by cutting poly shapes in square pattern combining with circular and square slots & placing a microstrip line feed. This design has been studied in iterations III. The radiation pattern of the aimed microstrip antennas maintained because of the self-similarity and centro-symmetry of the fractal shapes. With fractal shapes microstrip 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 pretend results of the case-by-case iterations are presented & discussed.
