ABSTRACT:
The present invention disclosed a partial-suspended open-line resonator for parallel-coupled line filter for size shrinking and well resonant response. The partial-suspended open-line resonator comprises one open conductive line, one etched ground structure having a lattice adjacent to the conductive line, wherein the lattice is formed on a ground plane. Furthermore, a part of the conductive line is suspended over the lattice.
