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.
