MIMO antenna system optimization for mobile applications using equivalent infinitesimal dipoles

In this paper, a very fast and accurate technique based on Infinitesimal Dipole Model (IDM) is used to minimize the correlation between two small F antenna elements. In this technique, a set of infinitesimal dipoles is used to represent each antenna element. Then, by using this model, the optimal location and orientation of each element is found to achieve the minimum correlation between antennas. It is shown that this technique is very accurate and efficient in computing the correlation between antennas compared to previous works.
