Research ArticleOpen accessIn the keywordsANALYSIS OF MICROSTRIP PATCHES ANTENNAS ARRAY BY USING A NEW BOND GRAPH TECHNOLOGYRiadh Mehouachi, Taghouti Hichem, Abdelkader MamiThis study is the only one that combines the microstrip patch antennas representing the microwave domain and the bond graph technique representing the automatic domain. In this study, we propose a new methodology to analyses the microstrip patch antennas arrays: It is the bond graph technique and the wave scattering formalism. This method helps us to achieve our purpose which … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 30 Jun 2014 · 6,555 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Overview of Direction-of-Arrival Estimation using an Antenna Array with Four ElementsLotfi Osman, Imen Sfar, Ali GharsallahThe Direction-of-Arrival (DOA) estimation techniques using antenna arrays are applied in large areas of research fields and have received great attention in literature. Mobile communication, Sonar and Radar are just some examples among a large number of possible applications. For example, in military application, it is very important to recognize the direction of any threat. Another example of commercial application … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 14 Dec 2012 · 7,777 accessesView PDF Cite
