摘要

The miniaturization of end-coupled microstrip slow-wave resonator filters using two high-permittivity ceramic substrates (with respective dielectric constants of 9.7 and 25.45) were investigated. The designed end-coupled structures were simulated using an IE3D simulator. The responses of the fabricated filters using Al2O3r = 9.7, tan δ = 0.000036) and newly developed 0.85MgTiO3-0.15Ca 0.6La0.8/3TiO3r = 25.45, tan δ = 0.00002) ceramic substrates were designed to have a center frequency of 1.8 GHz. The proposed filter showed not only a tremendous reduction in the insertion loss but also demonstrates a marvelous cut in its size.
