Abstract:
    This invention relates to a super broad band plane micro-strip filter including: a front part, a rear part and an input/output port, in which, the front part includes: interdigital capacitor units, a uniform transmission line and a medium plate, the two interdigital units are set at both ends of the medium plate, the unform transmission line is set at the middle of the medium plate, the input/output port has two ports connected with the capacitors, the rear part includes: a non-uniform DGS unit, a slot structure unit and an earth unit, the non-uniform DGS unit includes 7 arrayed non-uniformly in an approximate equidifferent sequence, the slot structure has three sets loaded at both sides of the even DGS unit, which applies front and rear circuit structure to realize high pass and low pass filters and reduce areas of circuits.
