Inset-fed Cantor Set Fractal Multiband Antenna Design for Wireless Applications

The design and analysis of a microstrip patch antenna exhibiting cantor set fractal geometry has been projected in this paper. Inset line feed technique has been employed in the design and the substrate material used is FR4-epoxy of relative permittivity 4.4 and thickness 1.6 mm. The designed antenna is simulated on electromagnetic simulation software Ansys HFSS (High Frequency Structure Simulator) version 13.0. MATLAB R2015a has been used for obtaining the parametric design values for the proposed antenna. The various performance parameters of the proposed Microstrip Patch Antenna (MPA) are evaluated and analyzed such as return loss, bandwidth, Voltage Standing Wave Ratio (VSWR), gain and radiation pattern. Simulation results establish that the projected antenna displays multi-band behavior which can effectively be utilized for wireless applications.
