“…The scale factor of antennas are 1/3 and the stage of iteration is n=3.The size of the substrate and the patch are the same. The dimensions of the patch and substrate are 54×54mm 2 . The thickness of the patch is 0.1mm and design from perfect conducting material.…”

“…The dimensions and wavelength of the antenna have the relation which is stated as the antenna cannot be efficiently radiated if the size of the antenna is less than /4 ( is the wavelength) because the gain, bandwidth and radiation resistance are reduced and so the size of the antenna is increased [1]. The fractals antennas are adopted for size reduction and multiband/wideband characteristics [2]. The size reduction is mainly due to the self-similarity property of fractal geometry and made of many copies of themselves with different scale factors.…”

The paper presents the designs of two Sierpinski carpet fractal antennas. The fractal properties have been applied in order to designs compact and wideband antennas. The antennas are analyzed in term of radiation parameters such as reflection coefficients, voltage standing wave ratio and radiation patterns. The results shows that the bandwidths of the antennas at the reflection coefficient less than -10dB are 5.5GHz and 7.25GHz ranging from 8.3GHz to 2.8GHz and 4.75GHz to 12GHz respectively. The directivities of antenna are 5.109dBi, 6.952dBi, 6.696dBi and the gains are 5.11dBi, 6.95dBi, and 6.7dBi. The bandwidth is largest at high resonance points with increasing the number of iterations. The proposed designs are suitable for wireless applications such as Wi-Fi,

Summary Over the last few years, fractal structure has been used in several engineering fields such as surface physics, telecommunication, fluid mechanics, and so forth. In telecommunication, often there is a demand for miniaturized patch antennas with fractal structures because it is capable of handling very high frequencies with its diminutive structure. The space filling capability of the fractal structures is used to effectively distribute the surface current all over the radiating material. Fractal structures have a better size reduction capability which aids a miniaturized antenna design. This article provides a generalized and detailed survey on fractal structures in a Euclidean space using iterated function system (IFS) in patch antennas. There are various techniques to design a fractal structure, namely, IFSs, escape‐time fractals, strange attractors, L‐systems, random fractals, and so forth. IFSs are widely used technique to construct a finite set of construction mapping on a complete metric space. The fractal geometries designed using the technique are Sierpinski carpet and gasket, Koch snowflake, deterministic tree/binary tree, Gosper island, Minkowski island, Cantor set, T‐square, and some space filling fractals. This paper deals with the above given fractal structures with their design expressions and shapes in recent developments and applications mentioned. The fractal geometries are used in MIMO antennas to abridge the mutually coupled radiators and improve the gain and efficiency of the antenna. This paper also analyzes the effects of fractal structures on MIMO antennas and discusses the ascendancy fractal structures by cross‐referencing the significant antenna parameters.

The objective of this paper was to design and analyze a dual wide band compact antenna for wireless application. Microstrip patch antenna limitation was overcome by using fractal geometry. The proposed antenna was designed with a radius of 15mm on a FR4 lossy substrate with relative permittivity of 4.4 and loss factor of 0.025. Measurement result showed that the antenna has a dual band of operation with bandwidth for return loss below -10dB of 1.84GHz (2.2GHz-4.07GHz) and 2GHz (6GHz-8GHz) which can be applied to wireless local area network (WLAN) and Ultra wide band applications.
