A Dual-band Dual-polarized Wideband Antenna For 4G/5G Sub-6GHz Base Station Application

A Wideband ±45° dual-band dual-polarized wideband antenna for the base station is proposed in this paper. By adding two inclined parasitic elements beside the simple dipole, its impedance bandwidth can be expanded. The designed antenna can cover the frequency bands from 1.65 to 2.4GHz (3G/LTE band) and from 3.24 to 3.68GHz (5G sub-6GHz band), and the reflection coefficient in the above frequency band is less than - 10dB, and the isolation is greater than 30 dB. The realized gain in the lower band is 7.3 dBi and the higher band is 6 dBi, which is suitable for base station antennas.
