Antenas com Tecnologia Quadband aplicadas aos sistemas irradiantes de telefonia móvel.

Abstract

This work aims to conduct a study on the evolution of radiating systems applied to mobile telephony, mainly addressing the Quadband antennas that are being widely used by mobile operators today. A detailed analysis of antenna characteristics is presented and, through data provided by the company Savenge Engenharia LTDA, a real case of replacement of Dualband antennas by the Quadband antennas of the mobile operator Tim is presented. Therefore, it is expected to present the Quadband technology applied to antennas in a practical way in order to prove the efficiency of the new radiating systems and to address important points for telecommunications companies operating in Brazil.
