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 &lt; 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.

Background: The CPW fractal antenna has been designed with hexagonal-cut, square-cut, triangular-cut shaped geometries on a composite material of Fr4 as a substrate with ϵr=4.4 of relative permittivity and 1.6mm thickness. Methods/Statistical analysis: In this paper, a comparative analysis for three different shaped CPW fractal antennas designed based on iterative function systems of self-similarity structures. To improve the gain, Frequency Selective Surface (FSS) is used for the fractal antenna design. Findings: The gain comparison of CPW fractal antenna with and without FSS of two different structures for three proposed CPW fractal shaped antennae are investigated. After implementing with FSS gain of the three antennas has improved with 3dB. The simulation results of return loss and gain are observed using the HFSS software. Application: The resonant frequency for the designed CPW antenna is 5.8 GHz and it is useful for WiMAX application. © 2017 IEEE.

Study on CPW antenna using fractal geometry for WiMax application

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). © 2015 IEEE.
