Dual-polarized filtering patch antennas have been proposed as a possible option for 5G networks in this paper. The impedance bandwidth is increased via a double-layer parasitic patch. Good filtering responses are achieved by packing resonant stubs into the differential feeding lines. It has been shown that the proposed antenna can function between 4.5GHz and 5.31GHz with less than $0.5 \mathbf{~dB}$ variation and an average gain of 9.2dBi through simulations and testing. There are more than 70 dB of port isolation and more than 25 dB of cross-polarization ratio in the system.
