Microstrip antenna is broadly used in the modern communication system due to its significant features such as light weight, inexpensive, low profile, and ease of integration with radio frequency devices. The fractal shape is applied in antenna geometry to obtain the ultra-wideband antennas. In this paper, the sierpinski carpet fractal monopole antenna (SCFMA) is developed for base case, first iteration and second iteration to obtain the wideband based on its space filling and self-similar characteristics. The dimension of the monopole patch size is optimized to minimize the overall dimension of the fractal antenna. Moreover, the optimized planar structure is proposed using the microstrip line feed. The monopole antenna is mounted on the FR4 substrate with the thickness of 1.6 mm with loss tangent of 0.02 and relative permittivity of 4.4. The performance of this SCFMA is analyzed in terms of area, bandwidth, return loss, voltage standing wave ratio, radiation pattern and gain. The proposed fractal antenna achieves three different bandwidth ranges such as 2.6-4.0 GHz, 2.5-4.3 GHz and 2.4-4.4 GHz for base case, first and second iteration respectively. The proposed SCFMA is compared with existing fractal antennas to prove the efficiency of the SCFMA design. The area of the SCFMA is 25×20 mm<sup>2</sup>, which is less when compared to the existing fractal antennas.

This paper is a new comparative study via numerical calculations and experimental measurements of various designs of fractal antennas. The geometry of the antennas dual?broadband (2.5/5.77 GHz and 2.4/6.18 GHz) for WLAN/ WiMAX applications is inspired by the Sierpinski carpet and the Minkowski. The simulated and measured results show a good agreement over the bandwidth. We also performed a comparison with current comparable antenna designs, demonstrating the superiority of the proposed antenna regarding applicability in telecommunication technology.

The use of multifunctional devices increases day by day. Mentioned devices, as smart tv, need appropriate and unified antennas which can meet required frequencies. Therefore, in this paper, a Sierpinski carpet microstrip fractal antenna in the second iteration is designed and fabricated for Digital Tv in UHF band and wireless wideband networks. It was verified that that the design of a fractal antenna based on the Sierpinski carpet is possible from a rectangular patch on iteration 0; however, it must be taken into account that the patch design must be carried out at a specific resonance frequency. Simulation is carried out using ADS simulator, and it was verified using a vector network analyzer. The proposed fractal antenna operates in the UHF digital TV range from 470 MHz to 683 MHz and in the 2.45 GHz to 2.4835 GHz range of broadband wireless local area network.

In this paper, a straightforward yet effective design methodology to design wideband antenna with band notched characteristics has been proposed. Sierpinski carpet fractal geometry has been used to realize the antenna structure. Co-planar waveguide feed is used with a novel structure to achieve larger impedance bandwidth and band notching characteristics. Proposed antenna is designed using High Frequency Structure Simulator (HFSS) on a low cost FR4 substrate (ɛr=4.4) which resonates at three frequencies 1.51 GHz (1.19-2.06GHz), 6.53 GHz and 8.99 GHz (4.44-9.54 GHz) while a band is notched at 10.46 GHz (9.32-11.92 GHz). The proposed antenna has an electrical dimension of 0.36 λm× 0.24 λm, here λm is the wavelength with respect to lowest resonating frequency of the antenna. The resonating and radiation characteristics of the antenna are verified experimentally. Further, investigations are made to achieve easy integration of the antenna to the monolithic microwave integrated circuits. For that the antenna has been designed on micro-machined high index Silicon substrate which improve matching and gain of the antenna. The results of the micro-machined Sierpinski carpet fractal antenna are highly convincing over the conventional FR4 based antenna.
