Design of Multi-Band Hybrid Fractal Antenna For Wireless Application

The proposed hybrid fractal antenna is designed to meet the demand of size miniaturization, multiband and low cost in Wireless Communication applications. The different two geometries such as Koch and Minkowski are combined to form a hybrid fractal antenna which have the ability to design a multiband compact size antenna with enhance bandwidth characteristics. The hybrid structure of the antenna is obtained by using Iterative function. Micro strip line feed is used to excite the patch of the antenna. The proposed shape is designed using FR-4 Epoxy substrate since it is readily accessible and inexpensive. The radiation pattern is omnidirectional and the VSWR is in the range between 1 and 2 for all resonant frequencies. With the aid of Ansoft High-Frequency Structure Simulator (HFSS) antenna parameters such as gain, VSWR, and return loss are noted. The designed antenna is capable of resonating at a different frequencies, including Bluetooth (2.12–2.95 GHz), WLAN (4.82–5.95 GHz), and ISM Bands.
