Abstract:
This paper presents the design and computer simulation results of a triplexer based on coupled resonators approach. It comprises 6 resonators yielding three passbands which are centered at 1.800 GHz, 2.077 GHz and 2.400 GHz covering the GSM, UMTS and IEEE 802.11b wireless bands. The specification of each band is Chebyshev with maximum reflection loss of -20 dB (ripple of 0.04321 dB). A Gradient-based local optimization technique is here utilized to determine the coupling coefficients by minimizing a proposed Cost Function. The triplexer can be built regardless of the type of resonator. It is only required that they be able to provide the optimized coupling coefficients.
