Filter coupling reinforcing structure

The invention provides a filter coupling reinforcing structure, which comprises a first resonance rod, a second resonance rod, a strip line structure and a conductor, and is characterized in that the two ends of the strip line structure are respectively arranged on the top surfaces of the first resonance rod and the second resonance rod so as to realize coaxial filter coupling; two ends of the conductor are respectively connected with the first resonance rod and the second resonance rod; wherein the inductive coupling strength between the first resonance rod and the second resonance rod is adjusted by adjusting the connection position of the conductor between the first resonance rod and the second resonance rod and/or the size of the conductor. In this way, low-frequency-band strong magnetic coupling can be achieved. 本发明提供了一种滤波器耦合加强结构，包括有第一谐振杆、第二谐振杆、带状线结构以及导体，所述带状线结构的两端分别设于所述第一谐振杆和第二谐振杆的顶面以用于实现同轴滤波器耦合，导体两端分别与所述第一谐振杆和第二谐振杆连接；其中，通过调整所述导体在所述第一谐振杆和第二谐振杆之间的连接位置和/或导体的大小，以调节所述第一谐振杆和第二谐振杆之间的感性耦合强度。如此，本发明能够实现低频段强磁耦合。
