Abstract
A capacitor structure is provided. In the capacitor structure, a signal electrode plate and an extension ground electrode plate are disposed on the same plane to form a co-plane capacitor structure. Due to slow wave characteristic, the resonance frequency of the capacitor structure is effectively raised and the capacitor structure may be applied in high frequency.
Claims7
A single-port capacitor structure, comprising:
- a first electrode plate having an opening;
- a second electrode plate, disposed at a side of the first electrode plate, wherein the second electrode plate and the first electrode plate do not locate on the same plane;
- a third electrode plate, disposed in the opening of the first electrode plate, wherein the third electrode late and the first electrode late locate on the same plane;
- a first interconnection for electrically connecting the second electrode plate and the third electrode plate;
- a fourth electrode plate, disposed at another side of the first electrode plate;
- and
- a second interconnection for electrically connecting the third electrode plate and the fourth electrode plate,
- wherein the second electrode plate and the fourth electrode plate have solid portions extending over the opening of the first electrode plate, larger in size than the opening of the first electrode plate.
