A Dual Band Dual-Polarized Sub-6GHz Base Station Antenna

This paper proposes a dual band dual-polarized base station antenna. The radiator of this antenna is a pair of modified crossed dipoles, which helps the antenna to operate at two frequency bands. A flat reflector instead of a shaped one is used to shape the radiation pattern of this antenna. The simulation and measurement results show that this antenna has good performance (VSWR <; 1.5 and isolation > 20 dB) at the 4G band and part of the 5G band. It also has good gains in the desired frequency bands.
