A Dual-Band Dual-Polarized Antenna for Small Base Station Applications
Cao Rong,Sim Chow-Yen-Desmond,Zhuang Jia-He 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.3
This paper proposes a dual-band dual-polarized antenna which can operate at both the 1.71–2.69 GHz band (3G/4G band) and the 3.3–3.8 GHz band (5G NR band 78). The main radiator (crossed dipoles) is meticulously designed to obtain the two desired bands of interest, and the fan-shaped feeding structures are used to obtain good impedance matching. The measured low band and high band operations was 49.8% (1.69–2.81 GHz, VSWR ≤ 1.5) and 14.8% (3.32–3.85 GHz, VSWR ≤ 2), respectively. The measurement results also show that this antenna has good isolation, stable radiation pattern, and good XPD.
