A Design of Rectangular Microstrip Patch Antenna Based on Fractal Geometry for Wideband Applications

Abstract

This manuscript presents the novel design of rectangular microstrip patch antenna based on fractal techniques for wideband applications. In this design, T-slots are introduced in rectangular patch geometry by varying the dimensions of slots which follow the concept of fractal properties. The HFSS V13 software is used to design, simulate and analyze the proposed antenna. Low cost FR4 glass epoxy substrate with thickness 1.6mm and dielectric constant 4.4 is used to design the proposed antenna at resonant frequency of 2.45GHz. Proposed antenna efficiently works on four frequency bands (2.0GHz, 6.5GHz, 8.4GHz and 9.7GHz) with acceptable value of gain, returns loss and also reports wide bandwidth. It exhibits the good omnidirectional and bi-directional radiation pattern at the frequency band of 2.0GHz. Proposed antenna can be used for different wireless applications such as point to point high speed wireless communication (5.925GHz -8.5GHz), bluetooth (2.41 -2.49GHz) and X-band application.
