摘要：A filter of the present invention comprises a multilayer substrate, two terminals,a ground conductor and a hybrid resonator. The multilayer substrate includes a pluralityof conductor layers and a dielectric configured to isolate said plurality of conductor
layers from each other. The hybrid resonator is disposed in the multilayer substrate andcomprises a first and a second resonant elements and a coupling strip connecting thefirst and said second resonant elements. Each resonant element comprises a signal via, agroup of ground vias and an artificial dielectric. Each signal via is disposed through themultilayer substrate. Each group of ground vias is disposed through the multilayersubstrate and configured to surround the signal via. Each artificial dielectric is disposed inthe multilayer substrate and between the signal via and the group of ground vias. Theartificial dielectric comprises a conductive plate connected to the first signal via and anisolating slit isolating the first conductive plate from the group of ground vias.
