Abstract
An dielectric laminated filter improves a skirt characteristic to shift am attenuation pole to a transmitting frequency band while maintaining the same band width of the transmitting frequency band and includes a dielectric block laminated with a plurality of dielectric sheets, ground electrodes formed on front and rear sides of the dielectric block, input and output electrodes formed on both sides of the dielectric body to be separated from the ground electrodes, an inductor pattern having two portions disposed parallel to the resonator patterns coupled to the input and output electrodes and a connecting portion coupling the two portions to induce an inductance coupling with the resonator patterns coupled to the input and output electrodes to improve a filter response characteristic by adjusting the inductance coupling.
