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

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.
