Single-pulse filter antenna array

The invention discloses a single-pulse filter antenna array, which comprises an upper dielectric base plate and a lower dielectric base plate, wherein the upper surface of the upper dielectric base plate is provided with a first metal layer, the upper surface and the lower surface of the lower dielectric base plate are respectively provided with a second metal layer and a third metal layer, a plurality of first metallized through holes are formed in the lower dielectric base plate, a plurality of second metallized through holes are formed in the upper dielectric base plate, the plurality of first metallized through holes, the second metal layer and the third metal layer define a dual-mold resonant cavity, the plurality of second metallized through holes, the first metal layer and the second metal layer define two second rectangular resonant cavities and four third rectangular resonant cavities, each second rectangular resonant cavity is coupled with the corresponding two third rectangular resonant cavities and is distributed in a shape like the Chinese character 'pin', and a radiation gap used for radiating signals is formed in the first metal layer corresponding to each third rectangular resonant cavity. The single-pulse filter antenna array has the beneficial effects that the loss is less, the structure is more compact, and the system efficiency is higher.
