The present invention provides a dual-polarized filtering antenna array. The dual-polarized filtering antenna array includes a first metal layer, a first substrate, a second metal layer, a second substrate, a third metal layer, a third substrate, a fourth metal layer, a fourth substrate and a fifth metal layer; a plurality of first metallized through holes are formed in the first substrate; a plurality of second metallized through holes are formed in the second substrate; a plurality of third metallized through holes are formed in the third substrate; a plurality of fourth metallized through holes are formed in the fourth substrate; the first metallized through holes, the first metal layer and the second metal layer enclose a first resonant cavity; the second metallized through holes, the second metal layer and the third metal layer enclose a second resonant cavity; and the third metallized through holes, the third metal layer and the fourth metal layer enclose a third resonant cavity, a fourth resonant cavity, a fifth resonant cavity and a sixth resonant cavity. The dual-polarized filtering antenna array of the invention has the advantages of smaller loss, more compact structure and higher efficiency.
