Design and Analysis of a Novel Five Face Fractal Antenna for UWB Wireless Applications

Abstract

The objective of this paper is to design and analyze a novel Five Face Fractal Antenna (3FA), for Ultra Wideband (UWB) wireless applications. Fractal technique is being used to overcome the limitations of microstrip antenna. The proposed antenna has been designed on FR-4 substrate with Ԑr=4.4, thickness h=1.6 mm and circular patch of 8.5 mm radius. The overall size of the antenna is 34×32 mm2. The impedance bandwidth of the proposed antenna is 7.90GHz ranging from 3.24 GHz to 11.14 GHz with a maximum gain of 4.83 dB and efficiency of 93.55%. Analysis of this antenna is done using High Frequency Structured Simulator (HFSS). The simulated radiation pattern of the proposed antenna has been observed as nearly omni-directional in azimuth plane. The proposed 3FA can be used for Wireless Personal Area Network (WPAN), Wireless Body Area Network (WBAN) and Home network applications utilizing UWB radio technology.
