TL;DR: The proposed antenna is designed by incorporating sierpinski fractals inside a circular ring of width 1mm which improves the impedance band width and radiation efficiency of the antenna.
Abstract: This paper presents a low profile sierpinski fractal antenna for ultra wide band applications. The proposed antenna is designed by incorporating sierpinski fractals inside a circular ring of width 1mm which improves the impedance band width and radiation efficiency of the antenna. The proffered antenna of dimensions 29×28×1.6 mm3 covering the frequency range of 3.7 to 14.3 GHz with radiation efficiency of 92% is fed by microstrip feed line. The radiation pattern is stable over the operating UWB range. Sierpinski fractal UWB antenna is designed and simulated using High Frequency Structure Simulator (HFSS).

TL;DR: A study of different models with fractal geometry implemented in Ultra Wide-Band (UWB) antennas design improves bandwidth, efficiency, and radiation properties, generating options that will serve as a starting point for the development and design of antennas in the future.
Abstract: In this article we present a study of different models with fractal geometry implemented in Ultra Wide-Band (UWB) antennas design. With different methods and geometric variants applied to this type of antennas, frequency ranges between 1-20GHz are obtained, generating an efficiency greater than 90% in its operating band, considering the variation of different parameters such as iterations, shape, slots, among other things; Bandwidths greater than 15GHz have been achieved, this has generated a wide range of applications for fractal antennas. An analysis was carried out based on the similarity of the models, the operating ranges, and the constructive characteristics, with the aim of improving bandwidth, efficiency, and radiation properties, generating options that will serve as a starting point for the development and design of antennas in the future.

TL;DR: In this paper, a printed planar elliptic patch juxtaposed with the ground pattern in a single substrate providing an ultra-wideband impedance bandwidth is presented, which is achieved by using a new impedance-matching technique of cutting a notch at a ground pattern opposite the microstrip line.
Abstract: A printed planar elliptic patch juxtaposed with the ground pattern in a single substrate providing an ultra-wideband impedance bandwidth is presented. The ultra-wideband property for the proposed antenna is achieved by using a new impedance-matching technique of cutting a notch at the ground pattern opposite the microstrip line. The concavity of the ground pattern serves as an effective means for adjusting the gap between the radiating element and the ground plane. With suitable size of notch chosen, the impedance bandwidth of the proposed antenna can be enhanced. Details of the proposed antenna design and measured results are presented and discussed.

TL;DR: In this article, a nano-arm fractal antenna was proposed for ultra wide band applications. But the shape of the fractal geometry, the number of iterations and number of nano-arms are the deciding factors for achieving wider impedance bandwidth.
Abstract: This paper presents the design of a nano-arm fractal antenna suitable for ultra wide band applications. The CPW-feed and fractal concept have been used to achieve the ultra wide bandwidth. The shape of the fractal geometry, the number of iterations and the number of nano-arms are the deciding factors for achieving wider impedance bandwidth. The experimental result of the fractal antenna exhibits ultra wideband characteristics in the frequency range of 2.55 GHz to 11.84 GHz corresponding to an impedance bandwidth of 131.77%. The measured radiation patterns of the proposed antenna are nearly omni-directional in the H - plane and bidirectional in the E-plane. The antenna can be useful for modern wireless communication, medical imaging and ground penetrating radar.

Abstract: Design and performance measures of a printed multistrip monopole antenna for ultra-wideband application are presented. The proposed antenna consists of six quarter wavelength strips of different resonant frequency combined in a manner to provide wide bandwidth and omnidirectional pattern. It operates in the frequency range 2.22∼11.67 GHz with impedance bandwidth (VSWR < 2) of 9.45 GHz and maximum gain of 6.07 dBi. The radiation pattern is nearly omnidirectional in the Azimuthal plane and bidirectional in the elevation plane and the consistency of the radiation pattern exists for almost all frequency in the operating band. © 2011 Wiley Periodicals, Inc.
