A Novel Smiley Fractal Antenna (SFA) Design and Development for UWB Wireless Applications



              The objective of the project is design and implementation of Smiley Fractal Antenna for Ultra Wideband (UWB) applications. Fractal antennas are simple, light weight and compact in size. The proposed antenna is employed with N-notch feed and modified ground plane, and is of compact size, fabricated on an FR-4 substrate with . The CPW feed used in the proposed system helps the antenna to achieve the bandwidth in the ration of 6:1.  The radiation pattern of the proposed antenna is omnidirectional with a maximum gain of 4.83 dB and efficiency of 93.55% is obtained.  For the design and analysis, Ansys HFSS software is being used.   The simulated results obtained show that the proposed antenna is a suitable candidate for multiband and wideband applications.
