A feeding device for a printed circuit board comprises a distributed capacity element comprising at least a first conductive strip and a second conductive strip separated from each other by a low loss dielectric layer, leading-out terminals coupled to the first conductive strip, a power source connected to at least one leading-out terminal of the first conductive strip, an electrolytic capacitor connected to the power source, and at least one non-polarized capacitor connected in parallel with the electrolytic capacitor, the second conductive strip being connected to a grounding circuit. A feeding element used in a feeding device comprises the distributed capacity element formed in an oblong shape by folding and coiling up the first and the second conductive strips layered as above-mentioned, and leading-out terminals connected to each of the strips, the element being enclosed in a container or encapsulated by plastic material. |
