Provided is a filter, comprising: an input port, an output port, a shielding housing, a dielectric, at least two layers of half-wavelength resonant units, at least one layer of quarter-wavelength resonant unit, and at least three layers of grounding resonant units. The half-wavelength resonant units and the quarter-wavelength resonant unit are connected in parallel between the input port and the output port. One end of the first layer of half-wavelength resonant unit is connected to the input port, and the other end is floating. One end of the last layer of half-wavelength resonant unit is connected to the output port, and the other end is floating. Both ends of the remaining half-wavelength resonant unit other than the first layer and the last layer of the half-wavelength resonant units are floating. One end of the quarter-wavelength resonant unit is grounded via the shielding housing, and the other end is floating. The grounding resonant units respectively surround the half-wavelength resonant unit and the quarter-wavelength resonant units. The inner sides of the grounding resonant units are floating while the outer sides are grounded via the shielding housing. Also provided are a filtering method and storage medium. |
