    • 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.
    • 电介质层压滤波器改善裙边特性,以将衰减极点移动到发射频带,同时保持发射频带的相同带宽,并且包括层叠有多个电介质片的介质块,形成在前侧和后侧的接地电极 介电块的形成在电介体的两侧的输入和输出电极与接地电极分离;电感器图案,具有平行于耦合到输入和输出电极的谐振器图案设置的两个部分,以及连接部分 两部分,以引起与耦合到输入和输出电极的谐振器图案的电感耦合,以通过调节电感耦合来改善滤波器响应特性。
