I am new in fractal systems. want to design a Microstrip fractal antennna using HFSS.so please help me by giving the tutorial, microstrip fractal antennausing HFSS.

Abstract

A microstrip fractal antenna has been introduced in the following paper. The iterations of hexagons are placed over one another in such a way that they do not overlap and each and every hexagon is clearly visible. The presented antenna has been fed with 50Ω probe. The antenna operates at a frequency of 0.6 GHz giving the input return loss of about -13.5 dB. The performance of the antenna has been evaluated using HFSS, V12, from Ansoft. The resulting antenna has a ground plane side each of 7cm. The antenna can find wide variety of applications in LTC5540, cognitive radio, radar systems, satellite communication, and highspeed digital clock generation. The paper aims to construct antennas using fractal patterns in order to obtain desired performance properties such as compact size and multi-band behaviour. The hardware has also been designed keeping in mind all the physical considerations and the results were obtained by plotting the radiation pattern on the graph paper using the antenna turn table.
