Research ArticleOpen accessPhrase in the titleA Novel Linear Array Antenna Based on UWB Slot AntennaFaten Ben Ghenaya, Ridha Ghayoula, Ali GharsallahThis paper introduces the novel Ultra-Wide Band (UWB) antennas for UWB applications. We used two different structures, the first is fed by micro-strip line and the second is a compact coplanar waveguide fed planar slot antenna. These designs are a small on planar antenna. The substrate used is FR4 that have the characteristics following: Permittivity εr = 4.4 Impulse Radio … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 25 Mar 2016 · 7,431 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAnalysis of Robustness for Convex Optimization Applied to Array Antenna Pattern SynthesisRichard Torrealba, David H. Covarrubias, Marco PanduroThis study presents an analysis of the convex optimization applied to the synthesis of the radiation pattern for linear antenna arrays. This study emphasizes the application of the convex optimization for the array pattern synthesis considering the simultaneous elimination of several zones interferences, reduction of the level of power in two space zones densely populated by interferences, as well as … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,566 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Hybrid Coupler Connected Square Array Patch Antenna for Wi-Fi ApplicationsA. Sahaya Anselin Nisha, T. JayanthyMicrostrip patch antennas being popular because of light weight, low volume, thin profile configuration which can be made conformal. Wireless communication systems applications circular polarization antenna is placing vital role. In this study we introduce a new technique to produce circular polarization. Hybrid coupler is directly connected to microstrip antenna to get circular polarization. Also gain is further increased by … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,638 accessesView PDFCite

Research ArticleOpen accessIn the abstractErgodic Capacity Analysis of Multiple Input Multiple Output Systems with Dual Hop Amplify and Forward Relay NetworksC. Poongodi, A. ShanmugamProblem Statement: In MIMO system, capacity mainly depends on the channel and the antenna characteristics. The capacity can be improved by proper design of antenna elements and choosing appropriate array configuration and the directive elements give more capacity than omni directional elements. The dual polarized antennas are better than single polarized antennas as the former can provide two information channels. … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,739 accessesView PDFCite
