Beschreibung
Zusammenfassung:	The utility model discloses a miniature wide stop-band low-pass filter which is mainly composed of a ground plate, an artificial dielectric layer, a separating layer and metal micro-strip lines. The metal micro-strip lines are disposed over the separating layer. Metal through holes are embedded in the artificial dielectric layer. Metal sheets are arranged on the upper surface of the artificial dielectric layer. The ground plate, the artificial dielectric layer, the separating layer and the metal micro-strip lines are successively overlaid and superposed. The filter of the utility model has a fine pass-band characteristic, is provided with a wide stop-band, and allows the requirement of the wide stop-band for a modern wireless communication system to be satisfied.
