DESIGN AND ANALYSIS OF MINKOWSKI FRACTAL ANTENNA USING MICROSTRIP FEED

In this paper, Minkowski fractal antenna for Bluetooth application has been designed. Apart from this, it can be used for various other applications as well because of its multiband feature. The antenna is fed by Microstrip feeding technique. Its advantage is that it can be easily fabricated as it is a just conducting strip connecting to the patch and therefore, can be considered as an extension of the patch. The proposed patch antenna is designed and simulated on IE3D simulation software and it is designed to operate in 2.45GHz band. Dielectric substrate with the permittivity €=2.2 (RT/Duroid 5880) with width of 1.588mm is used to make a resonant patch antenna of linear polarization. In this analysis, we have compared the antenna parameters such as gain, impedance, antenna efficiency, radiation efficiency, radiation pattern, polar plots, VSWR and Q-factor. Reduction in patch antenna size is achieved when performing fractalization of the main patch.
