RESUMO

The increasing demand for telecommunications services and the congestion of the radio frequencies spectrum have motivated the development of new devices with performance improved and small dimensions. This work will focus on dual-mode ring resonators and its applicability on the issue of assembly of filters. Initially, the model of the ring resonator and its resonance frequencies has been studied. Afterwards, a comparative analysis of different strategies of feeding have been made. Finally it has been studied the modeling of the structures with dual-mode rings resonators and a filter with this topology have been assembled. The simulations of this dissertation had been made by a developed software which implements the Finite Difference Time Domain method (FDTD).
