The invention discloses a small-sized dual-band dual-polarization filtering antenna, and relates to the field of antennas. Comprising a chamfered rectangular patch, a microstrip structure, a monopole array and a coaxial feeder line. The chamfered rectangular patch is arranged on the upper surface of the first substrate. The microstrip structure is arranged on the top of the second substrate as a coupling feed structure. The monopole arrays are embedded in the third substrate, and each monopole array is provided with a top load at the top of the third substrate. The coaxial feeder line vertically penetrates through the third substrate from the bottom of the third substrate, and the second substrate is connected with the microstrip structure. According to the small-sized dual-band dual-polarization filtering antenna, right-handed circular polarization radiation and omnidirectional linear polarization radiation are realized, no power divider or phase delay line is needed, the design complexity is reduced, and th
