The properties of the fractal have been used in order to design a less profile, better gain, light weight and narrow bandwidth antennas. Advanced wireless communication systems require antennas with lesser dimensions and wider bandwidth. The fractal antennas are preferred due to small size, light weight and multiband. In the designed antenna used FR4 glass proxy substrate having thickness of 1.6mm with dielectric constant Er of 4.4 and microstrip feeding line. The proposed antenna is 5.2GHz of size 18x14mm 2 .This antenna is suitable for wireless application such as WLAN, Details of the simulated results of the individual iterations is presented and discussed.

The design starts with a self-symmetry structure using conventional Vicsek snowflake-box fractal antenna. The same has been used in third iteration to achieve miniaturization. This proposed microstrip patch antenna (MPA) is resonating at 2.12 GHz with acceptable gain and broadside radiation. The miniaturization of about 87.26% when compared to conventional fractal MPA is achieved. The fractal unit cell is optimized for miniaturization and bandwidth by carrying out parametric study and applying the DGS shapes like rectangular and U-shaped slot etched in the ground plane of Vicsek snowflake-box fractal microstrip antenna. A fractal microstrip antenna is designed for wireless applications at 3.95 GHz. The fractal microstrip antenna is simulated using HFSS-V15 simulator. It is observed that the maximum size reduction of 87.26% is achieved ...

A self-similar property of fractal geometry is used, which is based on an iteration algorithm that reaches up to third iterations. It is simulated using the HFSS (High-Frequency Structure Simulator) software package version.15. A designed antenna is used to improve antenna performance, such as increasing bandwidth to 980 MHz and reducing the return loss from − 31.97 to − 23.4 dB. To excite the proposed antenna, a microstrip line feed is used. Up to 27% fractional bandwidth has been achieved in the antenna. This antenna can be used for a variety of wireless applications, including Marine radar and some communication satellites such as (Wireless LAN, Bluetooth, microwave devices/communications, and cell phone), as well as the lower portion of C-band.
