Fractal technology for multi-frequency antenna design in wireless communication

In the present scenario wireless communications systems need compact antennas which are capable of operating at multiple bands. To fulfil the requirement, we can use Fractal geometry antennas. Recent research work based on fractal antennas show that these self similar structures have their own specific characteristics that can improve certain properties when talking about low profile antennas. Here we will study, analyse, design and describe the plus, 3-iterations plus and modified 3-iterations plus shape structure, to obtain the required performance. The antennas properties, number of bands, the return loss, gain and radiation patterns will be studied to achieve the best performance. Simulations were done using Ansoft Hfss, implementations were done and results are presented.
