WIDE FREQUENCY BAND ANTENNA USING BASIC FRACTAL STRUCTURE WITH MICROSTRIP AND COAXIAL FEEDS

ELECTRONICS AND COMMUNICATION ENGINEERING

The use of fractal geometries has significant impacts on many areas of science and engineering; one of which is antenna. Fractal antennas for various telecommunication applications are already available commercially. The use of fractal geometries has been appeared to enhance several antenna features to varying extents. The objective of the project is to design and fabricate the Wide Band Frequency Antenna Using Fractal Structures resonating at 3.1 GHz to 10.8 GHz. Fractal concept to the hexagonal-shaped microstrip antenna that is designed low profile, light weight, flexible is introduced. The ansoft HFSS finite element electromagnetic computer package is used to model, simulate and analyze hexagonal fractal antenna with microstrip feeding and coaxial feeding that operates frequencies 3.1GHz to 10.8GHz. For designing the antenna FR-4 epoxy substrate with relative permittivity of 4.4 and thickness 1.6mm is used as the substrate. Microstrip feeding and coaxial feeding are compared and estimated the better performance. Different parameters of antenna such as gain, VSWR, radiation pattern, and reflection coefficient are analyzed and observed. The designed antenna can be used for different wireless point to point applications.
