Wideband fractal microstrip antenna for wireless application

Abstract

Enterprise Content Management (ECM) as a unifying concept is relatively new. ECM is based on the integration of a set of technologies each of which is still evolving. Not surprisingly, research is scarce and the market is still consolidating. As a result, integral ECM implementations are still rare.It is argued that, pending the widespread adoption and implementation of ECM, much can be learned from experiences with the implementation of Enterprise Resource Planning (ERP) software.Another reason for taking these experiences seriously is the growing extension of ERP-products with ECM-functionality. This extension may eventually result in an ERP-driven ECM-implementation or even in combined ERP/ECM products.Lessons learned from the implementation of ERP are that implementations may be compromised by a large number of legacy issues. It is argued that the same issues may similarly affect the implementation of ECM. Therefore, it is advised, with due adaptation, to take these issues into account in devising implementation strategies for ECM.

Inscribed Fibonacci Circle Fractal in a Circular Radiator for Ultra-Wideband Antenna Operation and Size Reduction

“…In this paper, the fractal inscribed into the conventional circular monopole is based in a well-known theory: the Fibonacci series, making the fractal easy to implement. Moreover, since the fractal has no abrupt transitions like those shown in [3][4][5][6][7], to mention some cases; the current distribution over the radiator does not change dramatically, keeping the impedance in a steady state. As a result, a wider bandwidth and a stable port matching are obtained.…”

“…A fractal, by definition, is a self-repetitive geometry which can improve the behavior of different structures, including antennas. At the beginning, the fractal structures were added to the radiator to obtain a multiband performance, since each part of it can resonate at a different frequency, and the whole structure behavior can be seen as a resonance overlapping as explained in [2][3][4].…”

“…This allows the antenna to have several resonance frequencies that can be selected and corrected by fractal model chosen. In recent years it has been shown in many studies (Best, 2003), (Kumar, 2010), (Kumar, 2012), that the use of fractal elements in the construction of antennas provides superior properties and performances, validating the idea that geometry is a key issue in determining the unique electromagnetic behavior of antennas substantially independent of frequency (Lincy, 2013). The present paper is included in the cycle of works published by the authors and dedicated to the design and analysis of some fractal antenna types (e.g.…”

“…Hu et al [19] proposed a novel rectangle tree fractal UWB antenna with dual band-notched characteristics operating in 3-11 GHz with two notch bands at 3.3-4.08 GHz and 5.04-6.03 GHz, respectively. Lincy et al [20] proposed a wideband fractal micro-strip antenna for wireless application.…”
