In this paper, a dual-band dual-polarized antenna with isolation enhancement is designed. The proposed antenna operates in the frequency range of 3.4–3.6 GHz and 4.8-5 GHz, where the center frequency of the high band (HB) is 1.4 times that of the low band (LB).
Therefore, this paper proposed a dual-band dual-polarized antenna for small base station applications that can cover the low band (3G/4G bands) and high band (5G NR band n78) at the same time. The main objective is to reduce the cost and space of future base station antenna that incorporates both bands of interest .
The base station antenna is a critical element in a communication system. A desirable base station antenna requires wide impedance bandwidth, stable radiation patterns, good isolation, and high cross-polarization discrimination (XPD) over the entire operating band.
A composite decoupling structure is proposed to ameliorate the mutual couplings for dual-band dual-polarized base station array. The structure consists of dual-band decouple surface combined with staggered dielectric surface and several meandered line resonators embedded on the ground.
