Radiation pattern changes in linear arrays of dipoles microstrip at 2.4 GHz in the presence of parasitic elements
Journal Title: TecnoLógicas - Year 2015, Vol 18, Issue 35
Abstract
This paper presents one of the results of research conducted to study the changes in the impedance input and radiation pattern parameters of the antenna systems, specifically linear arrays of microstrip dipoles are used; it is chosen as a parameter study the radiation pattern, the input impedance parameter will be presented in another publication. For their study, the system is modeled using numerical techniques with the help of the method of moments, in the conformation of the mesh array is used basis function given by Rao-Wilton and Glisson. The model is simulated with the Matlab® tool, the radiation pattern is determined for a dipole type patch and an array of these; the parasitic elements (dipoles) are located at different distances from the original array dipole and calculates the radiation pattern again, which are compared to those originally found. Finally, the results are presented and the advantage of these studies for handling radiation pattern in radiant systems is evident. Additionally, the presence of an element of symmetry is evident, this situation allows a considerable decrease the number of simulations, since the effect of the parasitic elements located on one side of the array of dipoles is similar to the effect that occurs when the parasitic elements are located on the opposite side.
