Abstract

A novel cross-coupled resonator filter with multilayer structure is presented in this paper. By using enhanced inner coupling structure and 3D layout, the resonator size is largely reduced, and high spurious frequency could be achieved. To validate the proposed topology, a cross-coupled 3D filter with inner coupling capacitor is easily fabricated on a normal printed circuit board. The measured results show the characteristics of small size, good stopband performance and high spurious frequency.
