Artificial magnetic conductor (AMC) is a periodic structure with in-phase reflection, which can be used in dual-polarization dipole antenna to reduce profile height. In this study, a low-profile dual-polarized dipole antenna with an AMC reflector is proposed by improving the AMC structure. The antenna consists of a pair of orthogonal planar dipoles with U-shaped slots, two T-shaped feeding lines, and an AMC reflector. The overall height is 0.132λ2.2 GHz. Experimental results show that the proposed antenna has a wider bandwidth than other antennas of the same type. The impedance bandwidth of this antenna is 52.3% (1.65 GHz to 2.81 GHz), and the proposed antenna also has the advantages of low profile, high port isolation (<-30 dB), and low cross polarization (<-27 dB). These features can meet the current needs of the telecommunications industry.
