Research ArticleOpen accessIn the keywordsDesign 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 abstractHigh Gain Multiband Stacked DRA for WiMax and WLAN ApplicationsSugadev Mani, Logashanmugam EdeswaranDielectric resonator antennas find widespread applications in high speed wireless systems because of low loss, compact size and light weight. In this study, performance of a multiband Dielectric Resonator Antenna (DRA) with higher gain and improved radiation efficiency for 3.8 GHz band Wi-Max, fixed point satellite links and 4.8GHz band 5G services and 5GHz wireless networks is presented. The proposed … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 3 Aug 2017 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerodynamic Noise Prediction Using stochastic Turbulence ModelingArash Ahmadzadegan, Mehran TadjfarAmongst many approaches to determine the sound propagated from turbulent flows, hybrid methods, in which the turbulent noise source field is computed or modeled separately from the far field calculation, are frequently used. For basic estimation of sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations (turbulent noise source field). A simple and … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,223 accessesView PDFCite
