“…There are various types of representations used for the fractal dimensions like Hausdorf dimension, topological dimension, self-similarity Dimension and Box counting method dimension etc. And the self-similarity property is the major parameter which is used for the analysis and characterization of the different fractal geometries [13]. The self-similarity parameter of the fractal geometry is defined as…”
his paper primarily focuses on various fractal geometries and their applications to antenna designs. Several natures inspired and human inspired fractal geometries are presented one by one. Their importance and design procedure are also briefly discussed. The dimensions of such fractal geometries are found using their mathematical modeling. Considering modeling and their corresponding shapes various low profiles, low cost, small size and, light weight antenna designs for various wireless applications are described. The broadband, wideband, and multiband nature of the design due to fractal application are discussed. Finally advantages, disadvantages, major applications, and future scope of such fractal geometries are mentioned.

“…Communication in the wireless medium can be done in the form of audio, video or graphical form using antenna [2]. The need for the communication in the wireless communication network has developed the idea of enhancement of the properties of Antenna.…”
“…So it is required to design a super UWB antenna with dual notched bands at 3.3 GHz–3.7 GHz and 5.15 GHz–5.85 GHz to prevent interference. Some dual band notched UWB antenna has been reported in the literature . In , dual band notched characteristics have been designed using two split ring resonators.…”
The design of a compact modified octahedron shaped dual band notched ultra wide-band antenna is presented in this article. The impedance bandwidth of the designed antenna has been enhanced by modifying the shape of the radiator by introducing fractal geometry and a modified ground plane. The proposed antenna offered an impedance bandwidth of 2.4 GHz-19.5 GHz (156% Fractional bandwidth). Two rectangular split ring resonator structures are introduced in the radiator to achieve two notched bands which ranges from 3.3 GHz to 3.7 GHz (WiMAX) and 5.15 GHz-5.85 GHz (WLAN) band. The antenna gain varies from 1 to 4 dBi over the operating band except the notched bands. The overall dimension of the designed antenna has a compact size of 33 3 40 mm
